Rice Husk Ash and Basalt Fibre-Based Sustainable Geopolymer Concrete in Rigid Pavements. A Review
From the last few decades, Geopolymer concrete has gained importance in the field of construction. Geopolymer concrete is a revolutionary product not only in the construction field but also it is environmentally friendly as it utilizes the waste by-products of industries like fly ash, GGBS, silica fumes, RHA, as pozzolanic material which is not having its binding properties, but the presence of silica and alumina in pozzolana gives rise to aluminosilicate hydrates in alkaline medium (prepared by mixing NaOH and Na2SiO3) of geopolymer concrete and provide a better replacement of cement in concrete, thus, decreasing the CO2 emission by the production of cement and in turn reduces the greenhouse effect. Therefore, the use of RHA and basalt fibre in geopolymer concrete in the rigid pavement can be carried out, and results should be compared with the control mix. 100% replacement of cement by silica-rich RHA in geopolymer concrete with basalt fibre as fibre reinforcement with various percentages as 1, 5, 10, 15, 20, and 25% in the rigid pavement can be done, which not provide only compressive strength but also increase flexural strength which is the compulsory requirement of rigid pavement.
