Mix proportioning and performance of a crushed limestone
Crushed stone sand has been identified as a potential substitute material for natural sand in making good quality concrete. The main objective of the present investigation is to determine an adequate mix design method and evaluate engineering properties of crushed limestone sand concrete mixtures in both the fresh and hardened sates.
Thicker concrete for things like foundations and larger mass concrete is usually a ''weaker'' mix of 1:3:6 which is one cement, 3 sharp/washed sand and 6 gravel/crushed stone. In all concrete just enough water should be added until the mix folds nicely off the paddles/tines inside the mixer.
