Historic concrete deals predominantly with concrete in Britain, but makes reference to discoveries and works in other countries where these have influenced practice in Britain. It examines the history of reinforced and prestressed concrete and also includes chapters covering military applications of concrete and its use in tunnels, roads and pavements, waterretaining structures and dams.
The production of precast concrete elements takes place under controlled conditions in enclosed factories. This makes the control of manufacturing, waste, emissions, noise levels, etc. easy compared with the same processes at a building site. The raw material .

The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel. This produces a light gray block with a fine surface texture and a high compressive strength. A typical concrete block weighs 3843 lb ( kg).
Production of Foamed Concrete The production of foamed concrete on a small scale is a fairly easy process which does not involve any expensive or heavy machinery and in most cases uses equipment that is already available for normal concrete/mortar production.
The quality of highstrength concrete is controlled by the quality and uniformity of the ingredients, and by the mixing, placing, and curing conditions. A high level of quality control is essential for those involved in the production, testing, transportation, placing, and curing of the concrete.
Concrete is essentially a mix of aggregates (sand and gravel or crushed stone) and paste (water and cement). Portland cement is a generic term to describe the type of cement used in almost all concretes. Production of cement remains under...
