Investigation of Strength and Workability in No-Fines Concrete

Abstract

The present paper reports the results of laboratory experiments carried out to investigate the properties of concrete such as strength, workability, etc. of No-Fines concrete which may offer the alternative to traditional non porous concrete. The mixes were prepared with a variable water cement ratios as well as varying sizes of coarse aggregate. The size of coarse aggregate taken for the study was 10 mm, 20 mm and a size varying from 10 to 20 mm. Cement contents used was 250 kg/m 3 , 275 kg/m 3 and 300 kg/m 3. The main aim of this study was to investigate the strength and workability of various mixes of No-Fines concrete and to propose an optimum proportion for desired strength and workability of porous concrete. Also study focuses on the effect of particle size of coarse aggregate on the strength and workability of No-Fines concrete.
