Roller-Compacted Concrete (RCC) Material Properties - ACPA

Compressive strengths of RCC are usually similar to those of conventional concrete (i.e. 4,000 - 6,000 psi). While these are typical compressive strengths of RCC, some projects have yielded compressive strengths exceeding 7,000 psi. The dense-graded aggregate structure and effectively low water-to-cementitious materials ratio (w/cm) help RCC

Aggregates for Concrete - Memphis

performance record, the aggregates should be tested before they are used in concrete. The most commonly used aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale,

Coconut Shell As Aggregate in Concrete Roof Tiles

2. The good indicators of coconut shell quality as aggregate of concrete roof tiles are particles, shape and texture, resistance to crushing, absorption and surface moisture, and light-weight. 3. The compressive strength gained higher than the conventional concrete roof tiles after 7th days. To view a complete report, please click the link below

Hollow Concrete Blocks: All You Need to Know

Concrete blocks are one such construction materials which help in achieving cheaper as well as faster construction than conventional bricks. The concrete blocks are available in two variations. 1) Solid concrete blocks and, 2) Hollow concrete blocks.In this article we are discussing both the varieties, yet, latter in more detail.
