this present work is an attempt to use quarry dust as partial replacement for sand in concrete. attempts have been made to study the properties of concrete and to investigate some properties of quarry dust the suitability of those properties to enable them to be used as partial replacement materials for sand in concrete.
dec 19, 2018 mix design and casting. concrete was created with a mix design of 1.3 according to BS 5328 using a rotating mixer.control mixes containing only regular concrete sand were first made; subsequently, waste FS replaced regular sand at increasing percentages per total sand mass, until
rock dust vs. sand under paving. when its time to pave or repave your walkway or patio, it is important to choose quality pavers that hold up to weather and foot traffic. just as important as
Dec 20 2019 · In recent days the demand for river sand is increasing due to its lesser availability. hence the practice of replacing river sand with m-sand is taking a tremendous growth. It is also inferred from the literature that replacement of normal sand with m-sand produces no appreciable increase in compressive strength due to the variation in the pore size of concrete at micro level.
