HIGH-STRENGTH STRUCTURAL LIGHTWEIGHT CONCRETE

Aggregate gradation significantly affects concrete mixture proportioning and workability. The particle size distribution, particle shape and surface texture are all important elements in the assurance of concrete quality and durability. Variations in grading materials, either by blending selected size aggregates or an adjustment of concrete

Pumice-Crete® Building Systems of New Mexico .

Pumice aggregate is mixed with only enough cement and water to produce a light concrete with a cured strength of 400 PSI. Only enough cement is used to coat the aggregate and bind it together where it touches. This is a lean mix and no attempt is made to fill the space between the stones.

Lightweight Aggregate Concrete - Properties, .

Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m3, when compared to normal concrete which is 2300-2400 kg/m3 and a proportion of the aggregate, should […]

Studies on Pumice Lightweight Aggregate .

The lightweight aggregate is an aggregate that weighs less than the usual rock aggregate and the quarry dust is a rock particle used in the concrete for the experimentation. The significant intention of the proposed technique is to frame a mathematical modeling with the aid of the optimization techniques. The mathematical modeling is done by minimizing the cost and time consumed in the case of ...
