Aggregate is a collective term for the mineral materials such as sand, gravel and crushed stone. By weight, aggregate generally occupies about 92-96 percent of the hot mix asphalt (HMA), and about 79-85 percent of the Portland cement concrete (PCC). Aggregate is also used for Base and Sub-base courses for both flexible and rigid pavements.

The cement content replaced with dolomite and fine aggregate replaced with copper slag from 5% to 25% at regular intervals of 5%. In the designed mix proportion of M30 grade concrete is 1:2.17:2.95.
Fine Aggregate: The most important function of fine aggregate is to assist in producing workability and uniformity of concrete mix. The fine aggregate also allows the cement paste to hold coarse aggregate particle in suspension. This action promotes plasticity in the mixture and prevents the possible segregation of paste and coarse aggregate.

Abstract : This paper attempts to study the use of dolomite rock sand (DRS) as fine aggregate replacement to crushed sand considering the increasing demand from construction industry and depleting crushed sand availability, in this regard DRS as fine aggregate (FA) replacement might be a sustainable option.Further- DRS was chosen for this study, considering its local …
This experimental study has been carried out to assess the effect of partial replacement of coarse aggregate by dolomite waste on workability, compressive strength and flexural strength of concrete. ... 10262–2019. Objective of study to analyzing physical property of fresh concrete that is workability & compressive strength, flexural strength ...
Concrete, the building material is becoming more valuable due to its high cost. To minimize its worth, new building industry improvements use extra elements such as marble powder. This partial replacement decreases expenses, saves energy, and protects the environment. In order to overcome the problem of dolomite waste in developing nations like …

The choice of the alkaline solution mainly depends upon the reactivity and the cost of the alkaline solutions. ... concrete waste made of dolomite aggregate was first included in the preparation of geopolymer-based on alkaline activation of brick waste. ... 2020; Vásquez et al., 2016; Shoaei et al., 2019), which can hinder their practical ...
The aim of this work is to further unfold the mechanism of the ACR reaction. For this purpose, concrete with silica-free dolomite aggregate was used and submitted to an accelerated dedolomitisation reaction at elevated temperatures in highly alkaline media or simply in aqueous media. By using silica-free dolomite aggregate, the ASR may be excluded.
The maximum increase in 28th day compressive and flexural strength was found to be 10.4% and 17.8% respectively. The percentage increase in split tensile strength was 39.8%. Use of dolomite powder decreases the cost of concrete. Since the cost of dolomite is less than that of cement.
The cost of concrete materials in building and civil engineering project has been a concern to the society. This requirement is drawn the attention of investigators to explore new replacements of ...

In this study, two types of coarse aggregate (granite and dolomite aggregate) were used. Total four mixtures were prepared with granite and dolomite aggregate of two different volumes, 1245 and 682 kg/m 3. The test results exhibited that the compressive strength of dolomite granular aggregate in concrete was found better than granite aggregate.
