Sep 11, 2016· Marble powder. Replacement of cement by marble dust for water concrete specimens are then allowed for 7 and 28 days for water curing . Then test will give us the nature of profile compressive strength variations and this variations can be effectively represent ed by means of graph. • Marble is industrially processed by being cut,...
aggregate. In the laboratory test, conventional fine aggregate was replaced at replacement level. A total of 18 cubes were cast, cured and tested. The strength development of the concrete mixes containing egg shell aggregates was compared to that of conventional concrete with sand as .
Keywords: Ordinary Portland Cement(43 Grade), Industrial Waste Fly Ash, Marble Dust Stone Dust _____ I. INTRODUCTION Nagar bhusana and Bai (2011) reported that crushed stone powder can be effective used to replace natural sand without reduction in strength of concrete at replacement level up to 40% (pofale and Quadori,2013) compressive ...

The primary aim of this work is to study the effect of incorporating the marble powder as a supplementary cementations material on the rheological and mechanical properties of SCC. ... Effects of marble powder as a partial replacement of cement on some engineering properties of selfcompacting concrete ... Fresh and hardened properties of green ...
· The concrete compressive strength with egg shell powder as cement replacement material increases up to 15 percent without silica fume. · Addition of silica fume also enhances the strength but in economical point of view only the egg shell powder replacement is sufficient enough for getting higher strength.
at 50% replacement at room temperature and net strength after loss due to hike in temperature was above the recommended strength value due to 50% replacement itself. This result gives a clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement.
Strength Behaviour of Mortar Using Fly Ash as Partial Replacement of Cement 99 Fly ash is comprised of the noncombustible mineral portion of coal. When coal is consumed in the power plant, it is first ground to the fineness of powder. Blown into the power
The 20% marble powder content is observed to be the optimum as sand and cement replacement amalgam for achieving the maximum concrete tensile strength but at 30% of marble powder replacement, will lead to a slight increase in tensile strength.
Concrete, Natural sand can be replaced with plastic waste by 10 to 20% to achieve green concrete. Sand can also be replaced up to 30% in the members of building which do not carry high load. Using plastic waste such as polyvinyl chloride (PVC), Polypropylene (PP), Polyethylene in concrete reduces the environmental issues and minimizes
The concrete specimens were tested for consistency, compaction factor and compressive strength at 28 days of age and the results obtained were compared with those of normal concrete. The results concluded the permissibility of using waste glass powder as partial replacement of fine aggregates up to 20% by weight for particle size of range
fine aggregate (sand) and cement were partially replaced with Granite powder and marble powder. The replacement is done by 5%, 10%, 15%, 20%, 25% of cement by marble powder and 5%, 10%, 15%, 20%, 25% of fine aggregate by granite powder to evaluate the effect of presence of these replacement materials on the strength of specimens.

They examine the possibility of using granite powder as replacement of sand and partial replacement of cement with fly ash, silica fume, slag and superplasticiser in concrete. The percentage of granite powder added by weight was 0, 25, 50, 75 and 100 as a replacement of sand used in concrete and cement was replaced with % silica fume, 10% fly ash, 10% slag and 1% superplasticiser.
One of the expected replacement for Cement in concrete are Lime Surkhi . According to the kind of binding material, the mortars are classified into the following five categories: i. Lime mortar. ii. Surkhi mortar. iii. Cement mortar. iv. Gauged mortar. v. Gypsum mortar. i. Lime mortar: In this type of mortar, the lime is used as binding material.
