Aug 08, 2014 Sheet glass aggregate used in concrete making leads to green environment. The objective of Present work is to find out the effectiveness of the fly ash and glass aggregate based concrete. In this investigation it was proposed that the use fly ash as cement replacement material and glass aggregate as fine aggregate material partially in concrete.
attempting to develop high performance concrete with the use of glass fibers as well as admixtures. While the combination of fly ash, alkaline liquids, fine and coarse aggregate and glass fibers resulted in the product called as Glass Fiber Reinforced Geopolymer Concrete (GFRGC).
Crushed glass was used as replacement for the fine aggregate in increments of 10 % up to 40 % wherein the sand was completely replaced with crushed glass. The various mix proportions were then moulded into bricks with the addition of water by hand moulding method of forming the bricks and sun dried followed by sprinkle curing over a period of ...
Jun 01, 2017 The glass powder replacement in cement was varied (0–25%). Mix proportion of concrete is shown in Table 6. Firstly, stone chips and sand were dry mixed for a minute. Appropriate quantity of glass powder was blended with cement in a separate container and then incorporated into the aggregate matrix (mixed earlier).

In the present study various tests on material such as cement, fine aggregate, coarse aggregate and the waste material from china clay industries were performed as per the Indian Standards. Material Used 1. Fine aggregate: a) Sand: River sand was used as fine aggregate. The size of the sand used is 4.75 mm and down size. The properties of
Hence, partial or full replacement of fine aggregates by the other compatible materials like sintered fly ash, crushed rock dust, quarry dust, glass powder, recycled concrete dust, and others are ...
This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and 100% by mass of aggregates.
with 10%, 15% and 20% fine aggregate replacement by demolition waste coarse aggregate at 7,14 and 28 days is comparable to that of referral concrete. The compressive strength of recycled concrete (CAR concrete) made using 10% of demolition waste coarse aggregate is almost similar to referral concrete.

Mar 30, 2018 Concrete, one of the most widely used construction materials in the world, is made up of 65 to 70 percent by volume of fine and coarse aggregates including sand, gravel and crushed rock. Global consumption of natural aggregate (NA) is estimated at 10 to 11 billion tons each year, of which approximately eight billion tons is used annually to ...
Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones. The coarse aggregate portion of RCA has no significant adverse effects on desirable mixture proportions or workability. Recycled fines, when used, are generally limited to about 30% of the fine aggregate portion of the mixture.
May 31, 2013 In practice, aggregates in stockpiles, plants, and in the mixture are rarely, if ever, at these moisture conditions. The absorption of the aggregate indicates the quantity of water which will be absorbed into the pore structure. Most commonly, aggregates will have a moisture content that is either below or above this absorption limit.
