Cement is a binding material, a substance that sets and hardens independently, and can bind other materials together. In ancient civilization the binding materials were of traditional type such as jaggery, lead, jute, rice husk etc, now in modern civilization cement is main binding materials. The use of concrete containing high volume fly-ash has recently gained popularity as a resource efficie...

This study investigates the progressions in mechanical properties of concrete by substitution cement Rice Husk Ash (RHA) conjunction with superplasticizers. husk is a by-product rice milling process, inexact generation 200 kg for every one ton rice. Diffusion matrix enhance concrete. investigation has been done to determine strength parameters various extents supplemented Ash. M20 grade (Design...

In this study two series of self compacting concrete mixtures were prepared with 100% coarse recycled concrete aggregates and different percentages of 0%, 20%, 40%, 60%, 80% and 100% fine recycled concrete aggregates. In series I and II the water to binder ratios were 0.50 and 0.45, respectively. The cement content was kept 350 3 m kg for those mixtures that don't have any Nano-Silica. To impro...

Concrete is the extensively used construction material in the world. However, environmental concerns both in terms of damage caused by the extraction of raw material and CO2 emission during cement manufacture have brought pressure to reduce cement consumption by the use of supplementary materials. The utilization of calcined clay, in the form of metakaolin (MK) in concrete has received consider...

-The simple replacement technique of cement by fly ash in concrete does not produce a concrete with desirable early strength which is a significant parameter of present day emphasis of speedier construction. Increasing the amount of flyash replacement slows down the strength development at early ages. For effective mix proportioning of fly ash concrete, cementing efficiency factor has to be tak...

Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

Disposal of waste into the landfill causes severe impact on environment. One products is ceramic waste. Ceramic has some excellent properties in its durability, hardness, and highly resistant to biological, chemical, physical degradation forces. These may make it suitable be used concrete. This study investigates effect fresh compressive strength lightweight foamed concrete with different perce...

The cementing efficiency factor k of a pozzolan is defined as the number of parts of cement in a concrete mixture that could be replaced by one part of pozzolan without changing the property being investigated, which is usually the compressive strength. This concept was proposed by Smith [1] and was initially applied in rational proportioning of fly ash concrete by using the ‘‘fly ash cementing...
