Concrete and cement motar are widely used now a days by construction industry. Keeping the environment in mind we have to manage the waste (industrial waste), but if these industrial waste are incorporated with cement concrete it not only increase the strength of concrete but also can decrease the cement content. In this research waste rice husk ash and waste paper sludge is used. The paper sludge production is a by product of paper making in the paper mill and rick husk is obtained from the processing of rice. By adding these components into the cement it increases the strength, flexural and compressive strength of concrete. The rice husk ash (RHA) and waste paper sludge were added to the concrete at varying percentages (15%, 10%) and (15%, 20%).

The concrete industries introduce various related techniques to integrate and utilize a waste material, which are easily acceptable, easily available, and economically within the buying powers of an ordinary people. Presence of such materials in cement concrete not only reduces the carbon dioxide emission, but also impact significant improvement in workability and durability. For control of concrete strength, IS method of mix proportion is used and considering this as basis, mix design for replacement method has been made. In the present study five different replacement levels namely 10%, 20%, and 30% of RHA are chosen. Large range of curing periods starting from 7days, 14days, and 28days are considered in the present study.
Concrete is no longer made of aggregates, Portland cement and water only it is not always incorporate so it requires at least one of the additional ingredients such as admixtures, supplementary Cementitious material or fibers to increase the strength and durability. Rice husk ash is one of the pozzolanic materials that can be blended with Portland cement for the production of durable concrete. Supplementary Cementitious materials prove to be effective to meet most of the requirements of durable concrete. Rice husk ash is found to be greater to other supplementary materials like silica fume and fly ash. In the current study an attempt has been made to investigate the strength parameters of M20 concrete (compressive and split tensile). For control concrete, IS method of mix design is adopted. Partial replacement of cement has been made with different percentage of RHA namely, 5%, 10% and 15%. Large range of curing periods starting from 7, 14 and 28 days are considered in the present study.
Study on concrete with partial replacement of cement by rice husk ash
IOP Conference Series: Materials Science and Engineering, 2016
Increase in the demand of conventional construction materials and the need for providing a sustainable growth in the construction field has prompted the designers and developers to opt for 'alternative materials' feasible for use in construction. For this objective, the use of industrial waste products and agricultural byproducts are very constructive. These industrial wastes and agricultural by products such as Fly Ash, Rice Husk Ash, Silica Fume, and Slag can be replaced instead of cement because of their pozzolanic behavior, which otherwise requires large tract of lands for dumping. In the present investigation, Rice Husk Ash has been used as an admixture to cement in concrete and its properties has been studied. An attempt was also done to examine the strength and workability parameters of concrete. For normal concrete, mix design is done based on Indian Standard (IS) method and taking this as reference, mix design has been made for replacement of Rice Husk Ash. Four different replacement levels namely 5%, 10%, 15% and 20% are selected and studied with respect to the replacement method.

Recent trend of technology is towards waste utilization and decrease in construction industries. In today’s industry concrete is major and versatile Building Material and in concrete, cement is that the pricely material and to trim its cost Agricultural waste is introduced in concrete. Rice Husk Ash (RHA), Wheat Straw Ash (WSA) and Saw mud Ash (Ash) is given as a partial substitution of concrete. Rice Husk Ash (RHA), Wheat Straw Ash (WSA) and Saw dust Ash (Ash) is replaced by cement up to 32% in concrete and their comparative is study is managed on the bottom of their compressive strength.
STUDY ON EFFECT OF PARTIAL REPLACEMENT OF CEMENT BY RICE HUSK ASH ON PROPERTIES OF CONCRETE
IRJET, 2022
This study aims to optimize the use of rise husk ash in increasing the strength of concrete. Rice husk ash is one of the major byproduct of rice mill industry. Rice husk ash has huge proportion of silica in it and behaves as a good cementious material due to the presence of silica in it. The fineness of rice husk ash particles allows it to get filled in between the voids in the concrete and thus increases the density of the concrete. The benefit of replacing cement with rice husk ash is that it is cheaply available, have high surface area, high silica content and high fineness modulus. In this study some proportion of cement is replaced with rice husk ash for M30 grade of concrete and the properties of new mix with 5 percent, 10 percent, 15 percent and 20 percent is compared with 0 percent replacement of RHA. The comparison of the results show that the compressive strength of concrete increased maximum upto 7.234 percent at 7 days and 8.978 percent at 28 days and split tensile strength increased maximum upto 8.367 percent at 7 days and 11.932 percent at 28 days at 15 percent replacement of cement with RHA. Also the flexure strength increased maximum upto 1.96 percent at 7 days and 1.06 percent at 28 days with 10 percent replacement of cement by RHA

Strength Performance of Concrete Produced with Rice Husk Ash as Partial Replacement of Cement
African Journal of Environmental Sciences & Renewable Energy, 2022
Concrete is the most common construction material with its major constituent being cement. The production of this Cement results in a lot of environmental issues which include the constant emission of CO2 gas. Reduction of this gas, preservation of natural resources needed in the production of the constituent of cement and subsequent sustainability of concrete structures have fueled the search for alternative cementing material to produce environment-friendly construction materials. Recently, supplementary cementitious materials like the agricultural by-products are used to replace a portion of the cement in concrete mixtures. The use of such CSM in concrete not only prevents these products from being land-filled which causes pollution but also enhances the properties of concrete in the fresh and hardened states. These supplementary cementitious materials with pozzolanic action react with hydration products in cement to form calcium silicate hydrate (CSH) thus enhancing and improving concrete quality and consequently reducing the cost of concrete production. One of such material is Rice Husk Ash (RHA). The study investigated the chemical composition of RHA as well as the specific gravity, workability, compressive strength, split tensile strength and flexural strength properties, with varying percentage of blended cement concrete and 100% cement concrete of mix ratio 1:2:4 and water-cement ratio of 0.5 were examined and compared. Slump test and compacting factor test was carried out to check the effect of RHA on the workability of fresh concrete. RHA partially replace cement in the order of 0%, 5%, 10%, 15%, 20%, 25% and 30% were cast. The concrete specimens were tested at the ages of 7, 14, 21 and 28 days. The optimal cement replacement was found to be at 10% RHA. This combination gave a compressive strength of 26.8 N/mm2. This is close to the control concrete with compressive strength of 26.9 N/mm2 at 28days hydration period. Therefore, rice husk ash can be used as a replacement for cement in concrete.

This study looked at how using small or large pieces of Rice Husk Ash and Waste Paper Sludge Ash can affect how strong and how much the concrete shrinks when it dries. When Rice Husk Ash (RHA) and Waste Paper Sludge Ash (WPSA) were added to concrete, more water was needed. However, the mechanical properties of the concrete were similar or better than the concrete made with just Ordinary Portland Cement (OPC). Finer RHA and WPSA gave the best improvements. Rice husk and waste paper ash made things shrink a lot because of tiny particles that cause it to happen. This research looked at using waste paper sludge ash instead of some of the cement in a kind of concrete called M20 mix. They tested different amounts of the ash (0%, 5%, 10%, 15%, 20%, and 25%) to see how strong it made the concrete. They tested the strength of the concrete up to 28 days after it was made and compared it to normal concrete. Waste paper sludge can be used as fuel because it has a lot of heat energy. Afterwards, the remaining ash can be used to replace some of the cement.
Variation in % of Rice Husk Ash with Cement for Improvement in Properties of Concrete
The Rice Husk Ash can be used as an alternative material instead of ordinary Portland cement. This technology could reduce the CO2 emission to the atmosphere caused by the cement industries. In the present investigation, a feasibility study is made to use Rice Husk Ash as an admixture to replace Portland cement in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive and Flexural). For control concrete, IS method of mix design is adopted and considering this a basis, mix design for replacement method has been made. Five different replacement levels namely 5%, 7.5%, 10%, 12.5% and 15% are chosen for the study concern to replacement method with range of curing periods starting from 7days and 28days are considered in the present study. Therefore, this paper aims at experimental study of variation of percentage of rice husk ash with cement for improvement in properties of concrete.
