Dolomite powder is treated as a substitute for cement if all of the aforementioned concerns and requirements are met in concrete Through a literature This study aims at exploring the benefits of using dolomite powder (DP) to improve the engineering performance of lowcement selfcompacting concrete (SCC) Enhancement of lowcement selfcompacting concrete with

Effects of dolomite powder on the properties of C30 and C50

Because the nucleation effect, microfiller effect and mix proportions design of dolomite powder were beneficial to the refinement of pore structure of concretes, and dolomite Based on the Weibull distribution, a damage model for concrete containing dolomite powder was proposed It established that concrete treated with An Innovative Material with Strong Frost

Use of quarry waste in concrete and cementitious mortars

The use of waste quarry dust to partially replace river sand was investigated (Gopalakrishnan et al, 2020) by studying the effects on the properties of lightweight foam concrete at five contents, starting at a 10% replacement and up to 50% replacement at 10% increments, in mixtures with only cement included as binderEffect of metakaolin and dolomite in high performance concrete is found out by replacing cement by dolomite in varying percentages of 5%, 75%, 10% and 125% and obtained optimum percentage ofStudy of concrete mix by adding Dolomite in conventional concrete

Polymers Free FullText On the Use of Dolomite as a

Polymers are being used in many applications all around the world However, there are some drawbacks in the properties of polymers that could hamper their usage in certain applications Therefore, a new Abstract This paper presents an experimental study on the effective use of high calcium fly ash (HCFA) and dolomite powder in geopolymer mortar (GPM) and concrete Trail HCFA GPM mixes were made with 10%, 20%, 30% and 40% dolomite powder The alkaline liquids used for polymerization are sodium hydroxide (NaOH) and Ambient cured high calcium fly ash geopolymer concrete with dolomite powder

Limitations of the hydrotalcite formation in Portland

This study focuses on the reaction of dolomite powder in combination with metakaolin in Portland composite cement pastesWe studied paste samples cured at 20 °C, 38 °C, and 60 °C for up to 1 year In these systems, the only magnesiumcontaining hydration phase of dolomite observed was hydrotalciteGGBSdolomite geopolymer concrete column showed better stressstrain behavior compared to cement concrete specimens Load carrying capacity of geopolymer concrete specimens were improved by adding steel fibres at 025, 05 and 075% by volume of concrete Ductility of geopolymer concrete was enhanced by 18%, 30% and 45% Behaviour of GGBSdolomite geopolymer concrete short column

Effect of partial substitution of cement with Dolomite powder on

Jain et al found that the durability of concrete was significantly improved when it contained 15% glass powder and 30% granite powder [21] Rodier et al added glass power residue to partially replace cement pastes and found that the mechanical properties of mortars improved when the glass powder replaced 10% cement by weight The highest crushing and tensile strength of concrete is observed for mix (MC40D5), which contains 5% dolomite replaced by cement and 40% copper slag replaced by fine aggregate The rate of hardening has increased from 15% to 20% with percentage increase in dolomite powder The Maximum concrete crushing strength is 4562 MPa An Experimental Analysis on Behaviour of Concrete with
