Behavioral investigation of low-cost rigid pavements

Abstract

In the prevailing work, an try has been made to evaluate the conduct of Alkali Activated Slag Concrete (AASC) compared to Conventional Concrete. For this, blend design for M20 grade concrete has been achieved as in keeping with IS 10262:2009 and the same turned into followed for AASC. The combination of 14M KOH and potassium silicate answer (K₂SiO₃) is considered to be solid AASC mixes. Preliminary investigation has been carried out on trial mixes with unique alkali activator modulus at variable potassium oxide dosages. The slag mixes are prepared with an activator modulus of 1.25 and 5% potassium oxide dosage well-known, shows better strengths. A boom in potassium oxide dosage beyond 5% reduces power parameters. The effects imply the homes of AASC +1% polypropylene fiber mix is barely better compared to control concrete and fulfil the strength necessities for rigid pavements. The application of alkali-activated binders will reduce the ecological disasters going on from current OPC manufacturing, in conjunction with powerful usage of business waste substances and conservation of common assets.
