Influence of Incorporation and Dimension of Expanded

For the production of this lightweight concrete, expanded polystyrene (EPS) associated with expanded clay sintered lightweight aggregates were used to replace nature aggregates. Materials characterization tests were performed, as well as tests of the concrete in the fresh and hardened state.

Expanded glass as light-weight aggregate in concrete - A

Use of sand and high strength aggregates combined with EGA is recommended for the development of high strength EGA light-weight concrete. Although the use of expanded clay, natural aggregates can increase the density of EGA concrete. Gradation of aggregates is a very influential factor for concrete mix design.

Comparative Between Lightweight Concrete & Traditional

High strength concrete is made by lowering the water cement (W/C) ratio to 0.35 or lower. • Aggregates which are used are:- expanded shale or clay, scoria, pumice, vermiculite or fly ash. Lightweight aggregate concrete, it depends on the materials used.

Mechanical properties of steel fibre reinforced

This paper presents basic information on the mechanical properties of steel fibre-reinforced light-weight concrete, manufactured using pumice stone or expanded clay aggregates. Results are presented for standard compressive tests and indirect tensile tests (splitting tests on cylinder specimens and flexure tests on prismatic beams using a three-point loading arrangement) under monotonically

Difference Between Lightweight & Heavyweight Concrete | Hunker

Lightweight concrete is made using aggregate whose density is less than 2,100 kilograms per cubic yard (or 131 pounds per per cubic foot), while aggregates with greater densities give rise to so-called heavyweight concrete. Expanded clay, slate and shale are common aggregate materials in lightweight concrete, while heavyweight mixtures use

Strength and durability assessment of self-compacted

This paper presents the effect of expanded polystyrene (EPS) aggregate on the strength and durability of self-compacted lightweight concrete (SCLC). SCLC mixes with different water/binder ratios and EPS contents (10, 15, 22.5 and 30 % by volume) were cured in two different curing regimes. Durability properties were investigated by water absorption, electrical resistivity, air permeability and
