A review on the utilization of fly ash - ScienceDirect

Autoclaved cellular concrete (ACC), is a light weight building product with high insulating value, which can be manufactured using 60-75% fly ash by weight. Fly ash, with carbon content up to 12% may be used, thereby, allowing the high volume use of ash from sources that do not meet ready-mix concrete specifications.

Properties of Gobi Aggregate and Sulfide-Rich Tailings

As shown in Table 2, the proportion of tailings is 4.39, the loose volume weight and dense volume weight are 1.55 t/m 3 and 2.23 t/m 3, and the porosity is 49.2%.On the basis of mineral process of Ashele Copper Mine and the chemical composition analysis of tailings, it is known that the relatively high content of Fe leads to the high proportion of tailings.

Oil-palm by-products as lightweight aggregate in concrete

The density of structural lightweight aggregate concrete (SLWAC) typically ranges from 1400 to 2000 kg/m 3 compared to that of 2400 kg/m 3 for normal-weight concrete (NWC). According to Neville ( ), the density of lightweight aggregate concrete lies between 350 and 1850 kg/m 3 , whereas ( Clarke, 2002 ) reported that the density of LWC

BARYTES CONCRETE FOR RADIATION SHIELDING: MIX

The basic requirements which must be met by concretes used for radiation- shielding applications are reviewed. High density, relatively high hydrogen content in the occluded water (0.4 to 1%), low heat of hydration, high specific heat capacity, high heat conductivity, a low value for the coefficient of thermal expansion and for the modulus of elasticity (resulting in a prevention of cracking

Concrete Mix Ratio: What Is It? What Is 1-2-3? ...And More

A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency. Water is not included in these ratios, though, because it can vary more

PDF Design of Concrete Pavement for City Streets

a concrete pavement is largely within the concrete itself due to its rigid nature, Because of the remarkable beam strength of concrete, heavy loads are distributed over large areas resulting in very low pressures on the subgrade. This makes it economically impractical to build up subgrade strength with thick layers of crushed stone or gravel.
