A method for filling a void using an aggregate material, such as mine tailings, the fill material being pumped from a site which is located remote from the void. A fluid, aerated material is formed by mixing the particulate solid material with finished foam. The aerated material may also include cement or another binder for applications requiring structural strength.

A cellular drainage structure is formed of a predetermined volume of a settable, water permeable, cellular concrete product. A concrete mix is formed of a uniformly graded aggregate in the size range from 1/16 inch to two inches and in a quantity corresponding to the predetermined volume; a cementitious component in the quantity range from 141 to 658 pounds per cubic yard of product;

Retaining walls are structures that hold or retain soil. Some typical materials that are used to construct retaining wall is concrete, sand, soil, crushed rock or boulders. The problem with using these traditional materials is that they are heavy which makes them harder to construct with both in terms of labor effort, resources and time.

Reading time: 1 minuteConcrete formworks are subjected to various loads and pressure. Concrete formwork loads and pressure calculations are described in this article. Formworks or molds are considerably important for building constrictions by holding fresh concrete mixture at place until it get required strength by which the self weight can be sustained. Generally, there are []
