Research paper thumbnail of Influence of chloride and sulfate solution on the long‐term durability of modified rubberized concrete

Journal of Applied Polymer Science, Jul 28, 2022

Mechanical and durability characteristics of rubberized concrete are assessed and compared to conventional concrete. Five contents of crumb rubber (10%–30% at 5% of increment) are utilized for partially replacing fine aggregate in concrete. The optimum amount of crumb rubber in concrete is revealed at a replacement level of 15%. The specimens remained in the crystalline form after being immersed in NaCl (sodium chloride), Na2SO4 (sodium sulfate), and MgSO4 (magnesium sulfate) solution, according to structural analyses by XRD (X‐ray diffraction). When rubberized concrete is submerged in both sulfate solutions with the same concentrations and for the same amount of time, the specimens immersed in Na2SO4 solution lose less weight and compressive strength than specimens submerged in MgSO4 solution. The losses in compressive strength of conventional concrete are 1.86%, 3.57%, and 4.82% when immersed in NaCl, Na2SO4, and MgSO4 solution. However, the losses are 1.67%, 2.79%, and 3.16% in rubberized concrete only at 24 weeks. Pozzolana‐based cement and after crumb rubber treatment, the rubberized concrete can resist chloride and sulfate solutions for a long duration.

RCA is a byproduct of the demolition of concrete structures that can be recycled as aggregate. Incorporating RCA into concrete reduces the environmental impact of waste disposal and reduces the carbon burden. Due to its pozzolanic properties, limestone, a sedimentary rock composed primarily of calcium carbonate, can be used as a substitute for cement. By substituting a portion of cement with limestone, the cement manufacturing process can substantially reduce carbon dioxide emissions. Metakaolin, a thermally treated form of kaolin clay, is yet another alternative material with pozzolanic properties. When used as a partial cement replacement, metakaolin increases the concrete's strength, durability, and chemical resistance. It also contributes to lowering hydration heat and mitigating alkali-silica reactions, ther...

It has a large impact on the construction industry owing to its better performance than that of conventional Portland cement concrete. This study aimed to identify the effect of curing conditions on the physical, mechanical, and microstructural properties of specimens using ambient curing and oven-curing. In the experimental analysis, we tested slump and setting time for physical properties, density and drying shrinkage for chemical properties, compressive strength, indirect tensile strength, modulus of rupture, Poisson’s ratio, and elastic modulus for mechanical properties, rebound strength, and UPVT for nondestructive and x-ray diffraction, and thermogravimetric analysis for microstructural analysis. After the experimental analysis, it was concluded that the density, Poisson’s ratio, and dry shrinkage were higher for ambient-cured specimens than for oven-cured specimens, whereas the compressive strength, indirect tensile strength, modulus of rupture, and elastic modulus of oven-cured specimens were higher than those of ambient-cured specimens. The nondestructive tests, rebound tests, and UPVT show that the oven-cured specimens are better in quality and strength than the ambient cured specimens. In microstructural analysis, x-ray diffraction showed that the oven-cured specimens had a lower intensity of mineral oxides than the ambient-cured specimens in microstructural analysis. The matrix of the ambient-cured specimens was thermally stable up to 800 °C and retained 92% of its original mass, whereas the matrix of the oven-cured specimens retained 94% of its mass up to 800 °C in the thermogravimetric analysis.

Research paper thumbnail of EFFECT OF SUPERPLASTICISER ON PHYSICAL, CHEMICAL AND MECHANICAL PROPERTIES OF THE GEOPOLYMER CONCRETE

Second ASCE India Conference on “Challenges of Resilient and Sustainable Infrastructure Development in Emerging Economies” (CRSIDE2020), 2020

Geopolymer concrete (GPC) is an innovative, eco-friendly, cementless and durable concrete, in whi... more Geopolymer concrete (GPC) is an innovative, eco-friendly, cementless and durable concrete, in which cement
content replace by the pozzolanic content that is full of silica and alumina mineral constituents. Geopolymer concrete
indirectly reduces the carbon footprints by the whole replacement of the cement because, in the production of cement,
large amount of carbon dioxide is emitted into the environment. Pozzolanic material like flyash, slag, are activated by the sodium
silicate and sodium hydroxide under the very high alkaline condition in the GPC mix designs at the time of casting.
Superplasticizers are used for reducing the water content from the mix design of the concrete, and reduction in water content
enhances the strength of the concrete. So, Superplasticizers have used the increment the strength of concrete with
retaining its workability. After the comprehensive survey, the references conclude that the best superplasticiser for the
GPC is SNF-based. In the comprehensive survey, the authors define that PCE-based superplasticisers increase the workability
of the GPC, but reduce the strength of the mixes at a very high level. So, in the experimental study, analyse the different
dosage of the SNF-based superplasticiser in the mix design of GPC. In the experimental investigation analysis, the effect of
the superplasticiser on the GPC physical, chemical and mechanical properties. The test for the physical properties
(workability) are the slump and compaction factor test, the test for chemical properties to find density, and for the
mechanical properties to find the compressive strength, flexural strength, splitting tensile strength and modulus of
elasticity of the GPC. After the experimental investigation, the Superplasticiser dosage with 1% by weight of the binder shows
the best properties against the other % dosage of the superplasticiser in the design mix.

Rubberized concrete provides more flexibility, impact resistance, and a lower unit weight than ordinary concrete. As a partial substitute for fine aggregate in concrete, six waste tire rubber crumb contents (0, 10, 15, 20, 25, and 30 percent) and particle sizes of 0.6-2.36 mm are utilized. Rubberized concrete's fresh, mechanical, and impact resistance characteristics are studied and found that by increasing the amount of rubber crumb in the mix, the fresh and mechanical characteristics are reduced. The energy absorption capacity of rubberized concrete increases with the increase of rubber crumb in concrete. However, the results aren't too concerning, up to a 15% rubber crumb replacement level.

The rubber particles used in the experiments are made of the recycled tire. The rubber waste is not easy to decompose even after long period of treating in landfill. Partial replacement of rubber in fine aggregate can be a way to utilize only where strength requirement is very low. Casting of cubes and beams with m30 design mix. The specimens were cured in water for required number of days before testing. Results were clear for reduction in strength with increase in rubber content.
