Feb 10, 2018 Type I Ordinary Portland cement (OPC) in accordance with ASTM C150, ground granulated blast furnace slag (GGBFS/slag), low calcium coal fly ash (FA), and the dolomite powder (DP) supplied from China were used to comprise the powder fraction of SCC/SCM.The physicochemical properties of the powder were shown in Table 1.Accordingly, the FA illustrated the chemicalget price
Dolomite powder obtained by pulverising the sedimentary rock forming mineral dolomite 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 extentget price
Dolomite powder, M-sand and Compressive strength, split tensile strength and flexural strength I. INTRODUCTION Concrete should not be confused with cement because the term, cement refers only to the dry powder substance used to bind the aggregate materials of concrete. Therefore, Concrete is a construction material composed of cement (commonlyget price
In this study a small trial is done to modify the properties of concrete by partial replacement of cement with dolomite powder varying from 0% to 10% with interval of 2.5% and fine aggregate withget price
aggregate or dolomite aggregate will be used for the coarse dolomite aggregate used in the concretes; Interface refers to the coarse dolomite aggregate - cement paste interface. In q)pendix A (photographs) and B (electron microprobe traverses and SEM-EDAX element maps), the following abbreviations are used: ce = cement;get price
Dolomite powder is mainly used in building materials ceramics glass refractories and other fields through the dolomite powder milling machinery processing as steelmaking conversion furnace refractory lining slagging agent cement raw materials glass flux ceramics fertilizer construction and decoration with stone and paint insecticide andget price
Abstract The 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 dolomitic inclusions or overburdenget price
Dolomite aggregate is a kind of refractory aggregate which is made of dolomite. It can be made into refractory such as dolomite aggregate concrete. Dolomite is carbonate mineral which takes the form of rhombohedral. The color of dolomite aggregate is usually white. Due to dolomite aggregate properties, dolomite is mainly used in making basicget price
By the effective utilization of dolomite powder as a construction material, the objective of reduction of cost of construction can be acheived. An attempt has been made to explore the possibility of using dolomite as a replacement material for cement. M30 grade concrete specimens were made by replacing 0, 5, 10 & 20% of cement with dolomite powderget price
the sedimentary rock which is mineral, dolomite can be used as a replacement material for cement in concrete up to certain percentage. Dolomite powder has some similar properties as like of cement. Use of dolomite powder in concrete can minimize the cost of concrete and may also increase the strength to some extentget price
Apr 24, 2018 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 cementget price
DOLOMITE POWDER was collected from the dolomite powder manufacturing factory. It was sieved by IS-90 micron sieve before mixing in concrete. Dolomite is a carbonate material composed of calcium magnesium carbonate CaMg (CO3)2. The term is also used to describe the sedimentary carbonate rock dolostone. Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with aget price
Jan 01, 2013 Effect of dolomite limestone fine powder specific surface on cement concrete compression strength at 7 days age When limestone content is optimal (25 % of binder weight), strength gain is higher than in the reference sample (0% additives) by 56 %get price
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 forget price
Dolomite powder is obtained by powdering the sedimentary rock forming mineral dolostone which can be used as a replacement material for cement in concrete. Dolomite powder has some similar characteristics as of cement. In the present study, sand is being replaced with Foundry sand and Dolomite powder is chosen as replacement for cementget price
