01-08-1970· Increasing the fineness of cement from 2700 to about 4000 cm2/g reduces the water requirement of concrete. Increasing the fineness of cement beyond an optimum limit increases the water requirement of concrete. 3. The workability of non air-entrained concrete is increased by increasing the cement fineness.
01-08-2007· This paper presents the results of a study that investigated the properties of concrete made with dune sand. Different control concrete mixtures using ordinary Portland cement (OPC) with a minimum design compressive strength of 40 N/mm 2 were prepared. The amount of fine aggregates constituted about 36% by weight of all the aggregates.
