The Process Of Repairing Angular Coarse Aggregate

If the depth of the repair exceeds 1 inch, the remainder of the repair process will consist of layering coarse, hot angular aggregate (cleaned and dried) at a rate of 25% – 55% by volume with the molten CrackMaster Mastic Gray until within -inch of the top of the repair. The bulking aggregate must be worked into the patch completely

    Mar 01, 2017 Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)

    Based on the grain size, the aggregates are classified into two types. Fine Aggregate. Coarse Aggregate. The fine aggregates are used in concrete as a filler material to fill the voids. The coarse aggregates are used in concrete to develop the strength of the element. The difference between the fine & coarse aggregate are listed below
