Chat Onlinequestion: is there an accurate, quick and inexpensive way to determine the percent of water in aggregate? answer: i batch up to 100 cubic yards of concrete a week for our in-house projects, using all applicable admixtures.Because the water in the aggregate varies, i have to guess at the amount of water for each mix.This takes unnecessary time and extra trial batches.
Chat OnlineAggregate serves as a reinforcement to add strength to composite materials such as concrete.Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate.Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm is sieve.
Chat OnlineSieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per is: 2386 (part i) 1963.In this we use different sieves as standardized by the is code and then pass aggregates through them and thus collect different sized particles left over different sieves.
