BSI is a new concrete technology that has a much higher tensile and flexural (bending) strength than standard concrete. It is a fiber-reinforced concrete that is combined with premixed dry components. It is much denser than standard concrete and structures built with it will need far less new concrete, perhaps as much as 80% less.

Quality Counts. Make sure that your concrete producer purchases good-quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates." A history of good performance of a local aggregate also provides an indication of how well the material performs in service.

Glass Fiber Reinforced Concrete (GFRC) or (GRC) is a type of fiber reinforced concrete. Glass fiber concretes are mainly used in exterior building façade panels and as architectural precast concrete. This material is very good in making shapes on the front of any building and it is less dense than steel.
The aggregate batcher also named as aggregate bins, is used for storage and batch the sand, gravel and crushed stone of the concrete plant. There are also many types of aggregate batchers, but most of them measured aggregate by weighing, some use the weighing hopper, some use the weighing belt.
Apr 12, 2018· Concrete is made up of cement and water plus an aggregate composed of sand and gravel. The sand and gravel do more than act as filler, though. The size and amount of gravel added to a bag of concrete also determines the product's volume, strength, and durability.
Coconut Fibre as enhancement of concrete Yalley and Kwan 55 and the sub-region that the coconut plant was cultivated. The specific objective of experimenting on coconut fibre as an enhancement of concrete is two fold. Firstly, to assess if the fibres of the
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...
The best aggregates to use for strength are crushed stone or crushed gravel. Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place. To improve the workability, many mixes

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Apr 18, 2019· Before you place your next concrete order, consider the following five reasons you should put fiber in your concrete. 1. Increase Toughness and Durability. If you want to increase toughness and durability of residential concrete, such as patios, polypropylene fiber can help.
Reactive powder concrete is extremely workable, durable and yields ultra-high strengths without using coarse aggregates. Reaching compressive strengths of 30,000 pounds per square inch (psi), this new-age concrete also has tensile strength with the inclusion of steel and synthetic fibers. Read more on reactive powder concrete.
Recently, however the development of polypropylene fiber-reinforced concrete (PFRC) has provided a technical basis for improving these deficiencies. This paper presents an overview of the effect of polypropylene (PP) fibers on various properties of concrete in fresh and hardened state such as compressive strength, tensile strength, flexural ...
