Aggregate Industries launches high early strength concrete

Aggregate Industries has developed a range of high early strength concretes which it says are specifically designed for structurual, void-fill, pavement and track bed applications. The Strike+ range, available in four different strength settings, is expected to offer high strength in various levels of consistency for a number of placement methods including pump, skip and direct.

Use of recycled concrete aggregate in high-strength ...

The results of a test programme to study the use of recycled concrete aggregate (RCA) in high-strength, 50 N/mm 2 or greater, concrete are described. The effects of coarse RCA content on the ceiling strength, bulk engineering and durability properties of such concretes have been established.

High-Strength Concrete - cement

In addition to selecting a high-quality portland cement, producers optimize aggregates, then optimize the combination of materials by varying the proportions of cement, water, aggregates, and admixtures. When selecting aggregates for high-strength concrete, producers consider the strength of the aggregate, the optimum size of the aggregate, the bond between the cement paste and the aggregate, and the surface characteristics of the aggregate.

Ultra High Strength Concrete - dailycivil

Aug 13, 2017 · Ultra high strength concrete can be easily produced by using high quality coarse aggregates, synthetic aluminous fine aggregates, and cement. Use of high temperature to increase the lime silica bond and use of spiral wrapping of concrete to induce triaxial stress are the techniques being tried to develop ultra high strength concrete.

While, this ratio for NWC and high strength lightweight aggregate concrete was found in the ranges of 11.6–13.5% and 9–11%, respectively. It can therefore be concluded that all the OPBC-OPS concretes had a similar flexural strength, and flexural to compressive strength ratio to the NWC and high strength lightweight aggregate concrete.

Effect of Aggregates On Strength Of Concrete | Engineering ...

Concrete strength increases when using dense gradation and increasing fines modulus of aggregates. By increasing fines modulus surface area of aggregates goes on increasing. With the increase in surface area more bond surface will be available and due to this stronger bond will be formed and also this requires less mixing water.
