1. Introduction. During construction, it should be remembered that high-quality concrete is necessary for building concrete structures. Cement, water, fine aggregate, and coarse aggregate can be mixed to make high-quality concrete [1].Good concrete, whether plain, reinforced, or pre-stressed, should be strong enough to support loads throughout …
shows the micro silica and sea sand. Here we use sea sand and micro silica in replace of some of the ne aggregates typically used in concrete. The rest of this article is sorted in the manner shown. Literature that is relevant to this discussion is included in Sect. 2. The sug-gested model is explained in Sect. 3. Section 4 provides a

The optimization of M-Sand with silica fume as a partial replacement for natural sand is discussed in this work. Compressive and split tensile strengths of concrete mixtures were assessed. Natural sand was substituted with manufactured sand in five proportions of 0, 10, 20, 30 and 40%, while silica fume was substituted for standard Portland ...
Sand from natural rivers is the type of fine aggregate that is utilised most frequently. ... 1610 kg/m3 and IV zone respectively. The chemical properties of quarry dust are silica, Alumina, Iron, Megnesium oxide and calcium oxide are 60 ... The combination that was achieved by replacing river sand with 30% Quarry Dust and replacing Fly …
This study reviews the fine aggregate (conventional Sand) replacements (such as Waste Foundry Sand, Graphite Tailings, Low-Density Polyethylene, Ceramic …
The present study evaluates the physico-mechanical and petrographic properties of stone dust and concrete using stone dust as a …
Fly ash (FA) and Quarry sand (QS) are some among the solid wastes generated by industry. The Quarry sand is one such material which can be used to replace sand as fine aggregate. To overcome from this crisis, …
The Quarry dust can be used as a fine aggregate by partial or fully replacement of river sand. Foundry sand is top-notch silica sand with uniform physical qualities. It is a side-effect of ferrous and non-ferrous metal throwing businesses [6].
Mining of river sand, thus, poses a heavy threat to the enivironment and ecological balance. Researchers have worked on crushed stone sand or quarry dust as a replacement to natural river sand in the concrete[6–8].Workability of concrete gets decreased when the river sand was replaced with Quarry Dust.
See the range of Building Aggregates in Middlesbrough. Quarries – Bulk Aggregates. Searching for an aggregate supplier who can supply in bulk? Thats us! From our depots in Yorkshire and the North East we deliver large quantities of aggregate (up to 30 tonnes). Our quarry sourced aggregates include a range of dry screened and washed products.
The rapid use of natural aggregates raises concerns about the preservation of natural aggregates sources. Furthermore, operations related to aggregate extraction and processing are the primary sources of ... Rakesh Sakale (2015) investigated the effects of replacing fine aggregate with waste glass powder by volume of cement in steps of …
In this work, the feasibility of the usage of quarry dust as 60:40 proportion of substitution of natural sand i.e (quarry dust replaces 60% of natural sand) in concrete. Silica fume is added as mineral admixture by 15% of weight of cement and steel fiber used in different percentage (0.5%, 1.0%, and 1.5%) to increase the tensile strength.
