The objective of the study is to establish that the powder sand can be used as an alternative of sand or mixed with sand in making medium grade concrete and mortar where high strength is no required .
The objective of this thesis is to find optimum percentage up to which these pozzolanic waste materials can replace OPC-43 grade cement to obtain maximum compressive strength. In this thesis OPC-43 grade cement is replaced partially by stone dust & granite powder simultaneously in the proportion of 5%, 10%, 15% & 20% by weight.
Substituting sand by stone dust will serve the waste management as well as the alternative material in concrete. The present research's aim is to find out the strength aspect of concrete by using stone dust as a partial replacement of sand. ... Ahmed AAM, Yusuf MA (2011)." Use of stone powder in concrete and mortar as an alternative of sand ...
Beyond the primary stone crusher and secondary crushers, screeners play a vital role in the stone-crushing process by grading the crushed material by size. …
1. Primary crushing equipment. Primary crushing is the first stage of the stone crushing process. At this stage, raw materials extracted through blasting or …
Results indicated at 75% replacement of crushed stone dust with waste glass powder at 5.10% bitumen content, 12.0kN Marshall stability value, 2.84mm Flow value, 4.0% Air voids, 72.3% VFB, and 2 ...
In order to obtain the aim of this study nine various mixes were used. The first mix was a control mix and did not contain any amount of waste glass powder while for the other eight mixes the cement and sand partially were replaced by waste glass powder in the ratios of 5%, 10%, 15% and 20% respectively.
The properties of concretes glass dust waste as fine aggregate were investigated in this study. Norfaniza Mokhtar and Nurul Atikah Jalani (2021) study expressed that Silica exists in waste glass components made it becomes a pozzolanic material and suitable to be used in a concrete mixture. The performance of the waste glass as fine aggregate was
Even reuse of so-called waste materials (e.g. stone powder, arsenic-contaminated sludge, etc.) can also give similar or sometimes batter strength that the conventional materials [13] [14][15 ...
Stone powder produced from stone crushing zones appears as a problem for effective disposal. Sand is a common fine aggregate used in construction work as a fine aggregate. In this study, the main concern is to find an alternative of sand. Substitution of normal sand by stone powder will serve both solid waste minimization and waste …
To eliminate the negative impacts of waste stone powder that arises from stone processing, the waste was recycled into aerated bricks with a porous structure that exhibited exceptional properties when applied in buildings. However, the pores easily absorb rainwater and dust, causing performance degradation and mold growth inside. In …
