The development of the compressive strength of pervious concrete using sugarcane bagasse ash and flyash

Abstract

This study's objective is to determine the effect on the characteristics of pervious concrete of partially replacing the cement in pervious concrete with either 10% fly ash and sugar cane bagasse ash as well as partially replacing the cement in pervious concrete with fine aggregates in varying proportions (ranging from 5%, 6%, 7%, 8%, 9%, and 10%). The construction of the various mixes required the use of fly ash from Class C, coarse aggregates ranging in size from 19 mm to 9.5 mm and 9.5 mm to 4.75 mm mixed in the ratio of 60:40, respectively, and a water to binder ratio that was maintained at 0.36 throughout the process. Moreover, the IS 10262-2009 method of mix proportioning was used in this experiment. With the use of the falling head method, we were able to determine the compressive strength, the total voids, the permeable voids, the density, and the permeability of the materials. This can be demonstrated by demonstrating that the range of compressive strength that was attained has potential applicability. In addition, the compressive strength was only marginally affected when cement was partially replaced by FA and SCBA (10%). On the other hand, the incorporation of fine aggregates at a percentage ranging from five to 5%, 6%, 7%, 8%, 9%, and 10% has resulted in an increase in strength that was previously described as “minor” to “high”. The incorporation of FA and SCBA into pervious concrete results in a reduction in the total amount of voids that are found inside the concrete.
