Copper slag as sand replacement for high

This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to . Concrete mixes were evaluated for workability, density, compressive strength, tensile strength

High-Performance Concrete, Chapter 17 - Memphis

High-performance concrete (HPC) exceeds the properties and constructability of normal concrete. Normal and spe-cial materials are used to make these specially designed concretes that must meet a combination of performance requirements. Special mixing, placing, and curing prac-tices may be needed to produce and handle high-perform-ance concrete. Extensive performance tests are usually

Preparation of high performance foamed

The titled high performance foamed concrete was developed from Portland cement, ultra fine granulated blast-furnace slag, pulverized fly ash and condensed silica fume by means of pre-foaming process. The resultant foamed concrete presents its thermal conductivity of about 0.16–0.75 W/(m · °C) and 28 d compressive strength of about 1.1–23.7 MPa when its mix proportion varies in the range

Comparative Study on performance of concrete with Natural

From Plot 1 it is observed that the compressive strength of robo sand concrete is more when compared to conventional concrete. The improvement in compressive strength is as high as 26.48 %. The increase in compressive strength is due to the sharp edged particles of robo sand providing better bond with the cement than rounded natural aggregate.

High Performance Concrete - an overview |

High-performance concrete may be defined as concrete with strength and durability significantly beyond those obtained by normal means. The required properties for concrete to be classified as high performance therefore depend on the properties of normal concrete achievable at a particular time and location. At the present time, high-performance concrete in developed countries usually refers to

Effect of Crushed Sandstone Sand on the

Aggregates are the major constituents in the construction industry. With natural sand and gravel resources being rapidly depleted all over the world, the needs of construction industry will have to be met increasingly from crushed sand as fine aggregates. This paper presents results of the laboratory investigation on high performance concrete (HPC) using crushed sandstone sand as 20%, 40%,

Which Sand is best for House Construction? -

River Sand is usually obtained from River Beds and Banks. It is usually very fine in quality and has a white-grey color. River Sand is good for all construction activities like concrete production and plastering as it is well graded. As per the Indian Standard codes, sand used in preparation of concrete and in plastering should ideally confirm to IS-383 Zone-II.

Ground granulated blast-furnace slag - Wikipedia

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing
