Effect of Change in Mixing Time of Mixer on Wet Density, Dry Density, Workability and Compressive Strength of M-20 Grade Concrete

Abstract

on actual construction site at the time of concrete production, mixing time of concrete mixer is kept as 2 minutes. This study was carried out on concrete properties by changing its mixing time. Ten concrete samples were prepared and tested with mixing time of mixture 1 minute, 2 minutes, and 3 minutes up to 10 minutes. Concrete of M-20 grade was prepared as per IS 456-2000. Using Nominal mix (guide lines of IS 456-2000) concrete was manufactured. Wet and dry density, workability and compressive strength were recorded for ten concrete mixes. Results obtained were presented in this paper.
