For any site building purpose: 10mm (3/8’’) Aggregrates, 15mm (5/8’’) Aggregrates, 20mm (3/4’’) Aggregrates, 40mm Aggregrates.
10mm (3/8’’) Aggregrates : Consisting of crushed rocks which are able to pass through a 3/8 rock screen, this aggregate base is suitable for the making of concrete due to its durability, grading, surface texture, and skid resistance. With these positive aspects, the coarse aggregate does much to influence the properties of the concrete it makes.
20mm (3/4’’) Aggregrates : This aggregate base, comprising crushed rocks that are able to pass through a 3/4 inch rock screen, is best suited for general construction use such as pipe bedding and filter media. The rocks in the aggregate base can consist of limestone, granite, and griststone.
