Other authors studied date palm reinforced concrete, reporting low durability performance that is related to fiber degradation when immersed in alkaline solutions (Kriker et al., 2008). Ghavami (2005) reported the case of a bamboo-reinforced concrete beam which was 15 years old and without deterioration signs.
Tremix Dewatering system is widely used in India for making RCC roads [Reinforced Cement Concrete Roads]. At many places in India, government regulation requires contractors to use the tremix methodology for making RCC roads, as dewatering enhances the strength of concrete roads and makes them last longer and withhold damage due to rains and heavy traffic.

In recent years, the Georgia Department of Transportation has spent time investigating roller-compacted concrete (RCC) pavement and its potential value to their program. The speed of construction, durability, and economy offered by roller-compacted concrete pavement were attributes that made it a long-term solution for GDOT pavement management ...
This sort of arrangement makes the lower section of the reinforced concrete also stronger against tension, which is the principal cause of the development of tension cracks in un-tensioned reinforced concrete. Since pre-stressing involves the use of jacks and tensioning equipment, the pre-stressed concrete is also cast in the factories.
How to Mix Concrete by Machine. Sometimes, for major jobs concrete mixer machine is used to mix the concrete. For major construction jobs with concrete, machine mixing is an absolutely essential method. A concrete mixer is a device that homogeneously mix cement, aggregates, and water to form concrete.
WHAT ARE DIFFERENT TYPES OF CEMENT CONCRETE MIXERS? ... These one bag / sack mixers have a tilting drum of 450 litres and can mix one bag of cement at a time and are used for small housing projects or repair works. They can be easily towed behind a pick up or small tempo and hence are very mobile.
Ready mix concrete requires less time as compared to site mixing (hand and machine mixing) and quality of concrete is also better than the site mixing. Further, it is very useful when you need huge volume of concrete per day, which otherwise is not possible to achieve with even more than one machines on site.

A slump test is a method used to determine the consistency of concrete. The consistency, or stiffness, indicates how much water has been used in the mix. The stiffness of the concrete mix should be matched to the requirements for the finished product quality. Slump is a measurement of concrete's workability, or fluidity.

Fiber reinforced concrete is a type of concrete that includes fibrous substances that increase its structural strength and cohesion. Fiber reinforced concrete has small distinct fibers that are homogeneously dispersed and oriented haphazardly. Fibers used are steel fibers, synthetic fibers, glass fibers, natural fibers, asbestos fibers and carbon fibers. The characteristics of fiber reinforced ...
Concrete mixtures can be designed to provide a wide range of mechanical and durability properties to meet the design requirements of a structure. The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures.
Behaviour of Plastic Mixed Reinforced Concrete Columns Under Axial Compression One of the main environmental problem today is the disposal of the waste plastics. The use of plastics in various places as packing materials and the products such as bottles, polythene sheets, containers, packing strips etc., are increasing day by day.
