Replacement of Cement with Dolomite Impact Factor 4.364
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

The Effect of Dolomite Additive on Cement Hydration
The effect of dolomite on alite hydration was investigated in order to elucidate the effect of dolomite addition in cement hydration. The rate of heat evolution both in cement dolomite and alite dolomite system was taken as a starting point.

THE EFFECT OF DOLOMITE AS LIGHTWEIGHT AGREGATE’S
dolomite’s mine potency, dolomite is only used as tanah urug and kumbung stone’s production. Until now there is no scientific data that shows the influence of dolomite when used as aggregate in concrete production. Therefore, the use of dolomite as concrete’s constituent materials is still need to be reviewed further.

Durable Concrete by Packing Density Method with Dolomite
dolomite powder in concrete we can reduce the cost of concrete and increase the strength. The replacement percentages tried were 0%, 5%, 10% and 15% by weight of cement. The compressive strength, flexural strength and split tensile strength of concrete with dolomite powder was compared with those of the reference specimens.

Effect on Concrete Strength due to Partial Replacement of
Dolomite is a preferred for construction material due to its higher surface hardness and density. Asphalt and concrete applications prefer dolomite as a filler material due to its higher strength and hardness. Dolomite has different grades and is available in different mesh sizes.

Effect of Dolomite Limestone Powder on the Compressive
Jan 01, 2013The purpose of this work is to describe the effect of fine ground dolomite limestone on important physic and mechanical properties of concrete. The present examinations indicate that the use of dolomite limestone as component instead of limestone is a viable solution for producing Portland dolomite limestone cement, especially for quarries with

Impact Resistance of GGBS-Dolomite Geopolymer Concrete
Impact strength plays an important role in structures like bridges, harbours, and barriers. The present stone investigates the impact resistance of GGBS dolomite geopolymer concrete using drop weight method. Procedures of ACI Committee 544 were used, and results were compared with that of cement concrete.

Understanding the hydration of dolomite in cementitious
Jun 01, 2018Impact of dolomite on the phase assemblage in hydrated systems. The ability of dolomite or calcite to provide the carbonate ions to form carboaluminate phases in Portland cement systems is dependent on their rate of dissolution. It has been shown that dolomite has a lower rate of dissolution compared to calcite [,,].

Dolomite Mineral Uses and Properties Geology
Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
