Abstract:
An experimental investigation is conducted to develop a standard procedure of the mix design of pervious concrete for strength and permeability aspects.The design is carried out by first fixing the % void that the required and then finding a method to control the voids in pervious concrete while casting samples. The compressive strength and permeability graphs with water cement ratios are developed for determination of the proper water cement ratio for the preparation of mix to get the requisite strength and permeability. The same thing is repeated with superplasticizer to get the mix design of pervious concrete with superplasticizer and study its effects on compressive strength, permeability, density of sample and % voids. At the end both the mix designs with superplasticizer and without superplasticizer are compared and conclusions are drawn.
This research investigates the effects of varying water-cement ratios and the addition of a polycarboxylate-based mid-range water reducing (MRWR) superplasticizer on the properties of pervious concrete. Mixes were prepared with water-cement ratios of 0.300, 0.325, 0.350, and 0.375 without superplasticizer and with water-cement ratios of 0.270, 0.300, 0.320, and 0.350 with the superplasticizer.
Compressive strength increased with the addition of the superplasticizer, reaching peak values at lower water-cement ratios compared to mixes without the superplasticizer. Permeability and void ratio showed a complex relationship with water-cement ratio, with optimized compaction and hydration occurring at specific ratios.
