Durability of concrete incorporating non-ground blast furnace slag and bottom ash as fine aggregate
Building and Environment, 2007
The paper presents investigation of how the usage of bottom ash (BA), granulated blast furnace slag (GBFS), and combination of both of these materials as fine aggregate in concrete affects the concrete durability. To assess durability characteristics of concrete, durability tests were conducted and the results were evaluated comparing with reference concrete. Three series concrete were produced. GBFS, BA and GBFS+BA are replaced the 3-7 mm-sized aggregate. Five test groups were constituted with the replacement percentages as 10%, 20%, 30%, 40% and 50% in each series. These by-products were used as non-ground form in the concrete. Durability properties of the concretes were compared in order to study the possible advantages of different replacement ratios. According to results, GBFS and BA affects some durability properties of concrete positively in case of it is used as fine aggregate. Resistance to high temperature and surface abrasion are positively affected properties. Capillarity, drying-wetting and freezing-thawing resistance of the concrete can be accepted to some extent. Properties of by-products and its replacement ratio are controlling the influence level and direction. Comparison of the SEM images and test results show that chemical and physical properties of GBFS and BA are the main factors affecting the concrete durability. It is concluded that it is possible to produce durable concrete by using GBFS and BA as fine aggregate. r

This paper presents an experimental study of combined effects of curing method and high replacement levels of blast furnace slag on the mechanical and durability properties of high performance concrete. Two different curing methods were simulated as follows: wet cured (in water) and air cured (at 208C and 65% RH). The concretes with slag were produced by partial substitution of cement with slag at varying amounts of 50-80%. The water to cementitious material ratio was maintained at 0.40 for all mixes. Properties that include compressive and splitting tensile strengths, water absorption by total immersion and by capillary rise, chloride penetration, and resistance of concrete against damage due to corrosion of the embedded reinforcement were measured at different ages up to 90 days. It was found that the incorporation of slag at 50% and above-replacement levels caused a reduction in strength, especially for the early age of air cured specimens. However, the strength increases with the presence of slag up to 60% replacement for the 90 day wet cured specimens. Test results also indicated that curing condition and replacement level had significant effects on the durability characteristics; in particular the most prominent effects were observed on slag blended cement concrete, which performed extremely well when the amount of slag used in the mixture increased up to 80%.
Experimental study on Strength Granulated blast furnace slag(GGBS) concrete Mix 50
The environment is being degraded due to the activities of human beings which are necessitated by the construction field (buildings, road, canals, dams, etc.), which is fast depleting the natural virgin sand lining the river bed. As a result ther need to find an alternate material, which is considered to be a waste product to replace these materials because the disposal the waste product such as GGBS. A twofold compensate on towards the conservation of environment takes place when a w materials such as GGBS is used for construction purpose. Thus, it is imperative that more studies and experiments be conducte on such waste products which serve as viable replacement for natural materials. The current paper focus mainly on the experimental findings of strength and durability of M50 grade concrete with partial replacement of GGBS.

Growth in the concrete production and the consumption increase in nature have led to a fast decline in available natural resources. A high volume of production has also generated a considerable amount of waste materials which have adverse impact on the environment. The scale of such problems makes researchers to investigate other sources of raw materials in order to reduce the consumption of energy and available natural resources. So in this regard, waste reuse and recycling are among modern society’s environmental priorities, and considerable effort is devoted to achieve these objectives and contributing in protecting the world against global warming. In the present experimental work Blast furnace slag and ceramic waste aggregates has been used extensively used as a replacement material for Portland cement and natural aggregates respectively in concrete materials to improve strength properties of concrete and brings environmental and economic benefits together, such as resource conservation and energy savings. M30 concrete grade was designed in which the cement was partially replaced by GGBFS by 25%,35% & 45% and natural coarse aggregates will be replaced by ceramic Tile waste by 15%, 30% & 45%. The workability and strength parameters were investigated. The results concluded that there is increase in workability and strength parameters up to certain percentage of replacement by Ground Granulated Blast Furnace Slag and ceramic waste Aggregates.

International Journal for Research in Applied Science and Engineering Technology, 2018
Concrete is the most widely used construction material all over the world. It is difficult to find out alternate material for construction which is as suitable as that of such a material from durability and economic point of view. In this project work, sand is partially replaced by industrial steel slag to compare the compressive strength of concrete with conventional concrete for the different curing period i.e. 3, 7 and 28 days. This project was done in three phases. In first phase fine aggregate was replaced by 10% of industrial steel slag. In second phase fine aggregate was replaced by 15% of industrial steel slag and in third phase 20% fine aggregate was replaced by industrial steel slag for M 30 grade of concrete. This paper presents an experimental investigation carried out to study the effects of industrial steel slag as a replacement of sand on strength development of concrete and optimum use of slag as a substitute material in concrete. In this study, concrete of M 30 grade were considered for a W/C ratio of 0.45 with the targeted slump of 100±25 for the replacement of fine aggregate with that of industrial steel slag. These concrete mixes were studied for the properties like compressive strength.

Concrete is the most popularly used substance for major infrastructure construction. Environmental issues are worsening as a result of the growing appetite for concrete caused by urbanization. Thus, there is a requirement for alternative construction materials. The main component of concrete, fine aggregate has a significant influence in mix composition. The largest consumer of material resources is the construction industry, which has caused the exploitation of natural sand. This circumstance prompted the development of novel alternative material. The motive of this investigation is to decrease the usage of natural sand by substituting it with Granulated Blast Furnace Slag (GBS). In this study, natural sand is partially replaced by GBS in 0%, 5%, 10%, 15%, 20%, 25% and 30%. The grade of the concrete is M20 and the w/c ratio is 0.5. The characteristics of the concrete like workability, compressive strength, split tensile strength and flexural strength are examined. The outcomes shows that the optimum replacement of fine aggregates by GBS is 20%.
