These will be cured for 3, 7, 28, 60 and 90 days, The results of the sieve analysis of both the fine and coarsePartial Replacement of Coarse Aggregate with Palm Kernel,kernel shell (PKS) in concrete and therefore production of lightweight concrete. Palm kernel shell is a waste and thus by using it environmentfriendly concrete is produced. For the construction of concrete, the materials which used are cement, sand, coarse aggregate and palm kernel shell. The ratio of these

Using crushed concrete as aggregate conserves resources

A new concrete mix can contain up to 100% recycled coarse aggregate, and recycled fines can replace 10% to 15% of sand. Recycled aggregate also can be used in concrete shoulders, median barriers, and granular and lean concrete base layers.The impact of granite and sand as coarse concrete ,the impact of granite and sand as coarse concrete. an experimental investigation on strength of granitefines concrete. water for 3, 7, 28, 60 and 90 days with sand .

Effect of Copper Slag as a Fine Aggregate on Properties of

applications for reusing copper slag is in concrete production. Many researchers have studied the effect of replacement of alternative to coarse aggregate/fine aggregate used in concrete and mortars R R Chavan D B Kulkarni has investigated the performance of high strength concrete (HSC) requirements for concrete sand.On the classification of mixed construction SpringerLink,Most of the water absorption occurs in the first 10 min, regardless of the aggregate's total porosity. Thus, a 10min presaturation in water was adopted for the coarse aggregates in concrete production to prevent the aggregate from influencing the concrete's water demand [4, 5].
