Aggregates SlideShare
Fine Aggregates “Fine aggregate” is defined as material that will pass a No 4 sieve and will, for the most part, be retained on a No 200 sieve 11 Types Of Fine Aggregates Sand Stone dust Cinder Surkhi 12 Sand The first type of fine aggregate is Sand Sand is little particles of silica Crushed Stone Sand / Artificial Sand It is a substitute for River Sand, fine aggregates which manufactured by crushing either granite or basalt rock using 3 stage crushing process 14 Classification on the basis of size of particles 15 Fine sand The sand passing through a sieve with clear openings of 15mm is known as fine sandSand SlideShare How is the global sand and gravel aggregate market performing? As the demand for aggregates from China, Africa, Latin America, Europe,etc will continue to rise, and the price of artificial sand will also increase, the outlook for the global aggregate market for sand and gravel is Artificial Sand What Is It and How to Make It Fote
Artificial Aggregate an overview ScienceDirect Topics
2152 Artificial aggregates Studies on FA and its potential as an artificial aggregate are not new to the industry [23] Primarily two forms of artificial aggregate using FA are reported in the literature, sintered FA lightweight aggregate and FA cenosphere aggregate, as coarse and fine aggregates, respectively [24] The sand is coarser than silt and finer than gravels The major compound that consist is sand is silica The silica is occupying in the sand in the form of quartz The diameter of the sand particles ranges from 0075mm to 4,75mm The sand is used as the fine aggregates Types of AggregatesNatural and Artificial Aggregates 600µm and 125mm for fine and coarse aggregates respectively Thus, the sand used was normal sand since it lies within Zone II of geological grading Figure 5: Test of Cylindrical Specimen for Splitting Tensile Strength The particle size distribution conducted in accordance with the BS882 were used to plot grading curve for the fine and coarseEffect of Sand Fines and Water/Cement Ratio on Concrete
