Dolomite is used in concrete to reduce the consumption of cement. The purpose of this project is to determine the mechanical property of dolomite and vermiculite in concrete. Lack of fine aggregate can be solved by using of Vermiculate. Dolomite is replaced in the percentage of 10 percentage and 15percentage with the weight of cement.

Dolomite powder at present time,does not form on the surface of the earth; yet massive layers of dolomite can be found in ancient dolomite rocks. Dolomite is a .
The studies of hydration process in the mixtures of cement with limestone powder, dolomite powder and limestone â€" dolomite additive were reported by NocuÅ„-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.
compressive and split tensile strength of concrete with dolomite powder was compared with those of the reference specimens. The results indicate that replacement of cement with dolomite powder increases the compressive and split tensile strength of concrete. KEYWORDS: Dolomite Powder, Mix Design, Compressive Strength, Split Tensile Strength I.

A dolomite composite admixture preparation method and novel application; the dolomite composite admixture preparation method comprising: levigating dolomite to particles basically the same as silicate concrete; adding a specific proportion of dolomite powder by mass of silicate concrete; adding a specific equivalent amount of alkali-containing substance of sodium oxide by mass of dolomite ...
Dolomite is chosen for many construction and building product applications due to its hardness and density. A few applications applications are: Asphalt and concrete mixes in a wide variety of construction applications such as highways, airport runways, parking lots, sidewalks, curbs, and residential streets and roadways, just to name a few.
It's a cost-effective option to natural stone cladding for exterior surfaces. It also offers the advantages of being weather-resistant, long-lasting and low maintenance. All it takes to prepare the perfect mix is one part of Birla White Cement and one part of coarse dolomite powder/quartz sand. Pigments could be added to get the desired shade.

Using 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 concrete mix ...
It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap, or fill. It is also calcined in the production of cement and cut into blocks of specific size known as "dimension stone." Dolomite's reaction with acid also makes it useful.
Replacement of cement with dolomite powder is found to improve the strength of concrete. The optimal replacement percentage of cement with dolomite powder is found to be 5% and at this replacement level, the maximum increase in the 28th day compression and flexural strength were found to be 5.84% and 2.73% respectively.
The invention relates to a preparation method and new application of a dolomite complex admixture. A concrete complex admixture with impermeability is prepared by grinding dolomite to the particle size which is basically the same with portland cement, mixing a certain proportion of dolomite powder according to the weight of the portland cement and mixing a certain equivalent of alkali ...
Dolomite powder obtained by powderising the sedimentary rock forming mineral dolostone can be used as a replacement material for cement in concrete up to certain percentage. Dolomite powder has some similar characteristics of cement. Using dolomite powder in concrete can reduce the cost of concrete and may increase the strength to some extent. This

May 18, 2019· amount of dolomite increases in the mixture, the compressive strength decreases. The minimum amount of the compressive strength 11.19 MPa was gained when 25% dolomite powder was used in the mix 9. This showed that the compressive strength of concrete decreases as we increases the percentage of dolomite powder and nano silica.
