Replacement of Cement with Dolomite Powder: An

Use of dolomite powder in concrete can minimize the cost of concrete and may also increase the strength to some extent. This project work examines the possibility of using dolomite powder as a partial replacement material to cement. The replacement percentages tried were 0%, 10%, 20%, 30% and 40% by weight of cement. The compressive, split tensile, flexure strength & modulus of elasticity of

The Effect of Dolomite Additive on Cement Hydration

The studies of hydration process in the mixtures of cement with limestone powder, dolomite powder and limestone dolomite additive were reported by Nocuń-Wczelik et al. [6]. In the pastes hydrating with fine grained dolomite powder the crystallization of products is accelerated and as a consequence the strength development is improved. Because of the modification of microstructure the

Effect of dolomite powder on the hydration and properties

that the addition of dolomite in powder form to cement performs a comparable compressive strength to Portland-limestone cement [1,2]. Moreover, similar to limestone, dolomite may be involved in hydration of cement, resulting in the formation of carboaluminates and the stabilization of ettringite. Besides, Mg released from dolomite is considered to interact with the cement aluminates to form
