INFLUENCE OF MINERAL ADDITIVES PROPERTIES OF CONCRETE
Journal Title: Structure and Environment - Year 2016, Vol 0, Issue 2
Abstract
The article discusses the results of laboratory tests on the impact of dolomite mineral dust on the rheological properties of the concrete mix. The addition of mineral dust rise to an overall improvement in the studied parameters (absorption, capillary), by sealing the grout. The impact of their actions on the rheological properties depend largely on the grain composition and the degree of grinding. Rheological properties of concrete mixtures of flours stone depends on the amount and geometrical properties of these additives. The use of additives enforces the need for their treatment by the process of drying, screening and segregation. The effect of the presence of meal stone to change the rheological properties of fresh concrete (density, consistency) and hardened concrete parameters (compressive strength, water absorption, capillary action).
