Concrete | Definition, Composition, Uses, Types, & Facts
Aggregates are generally designated as either fine (ranging in size from 0.025 to 6.5 mm [0.001 to 0.25 inch]) or coarse (from 6.5 to 38 mm [0.25 to 1.5 inch] or larger). All aggregate materials must be clean and free from admixture with soft particles or vegetable matter, because even small quantities of organic soil compounds result in chemical …

Advantages and Disadvantages of Concrete
Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials act as a binder. The most important binding materials are cement and lime. Inert materials used in concrete are termed aggregates.The most common aggregates are sand, brick chips, stone chips, gravel, shells, etc. Concrete …
Experimental Investigation of Properties of Concrete …
Urbanization in rapidly developing countries (e.g., China) is generating a tremendous amount of construction and demolition (C&D) waste. Recycling of concrete waste has become a solution to treat the large amount of C&D wastes generated, to save natural resources for concrete production, and to protect the urban environment [1, …
Improvement of the mechanical performances of concrete cylinders
The present study deals with crush tests of concrete cylinders confined by shape memory alloy (SMA) wires. Two cases were considered. First, an active confinement was achieved by wrapping a wire previously prestrained in martensitic state and then subjected to the memory effect. Second, a passive confinement was obtained by using …

Advantages of Precast Concrete and Factory Production | Quality …
Although mould types suited to the method of production (e.g. rigid moulds with few fold-down parts) demand a design approach that suits the production, this does lead to high mould reuses. Another reason for precast concrete construction was undoubtedly the reduction or total elimination of scaffolding costs.
