FERRO-CEMENT
The term ferro-cement implies the combination of ferrous product with cement. Generally this combination is in the form of steel wires meshes embedded in a portland cement mortar. Wire mesh is usually of…
CELLULAR CONCRETE
It is a light weight concrete produced by introducing large voids in the concrete or mortar. Its density varies from 3 kN/m3 to 8 kN/m3 whereas plain concrete density is 24 kN/m3. It…
FIBRE-REINFORCED CONCRETE (FRC)
Plain concrete possesses deficiencies like low tensile strength, limited ductility and low resistance to cracking. The cracks develop even before loading. After loading micro cracks widen and propagate, exposing concrete…
REINFORCED BRICK CONCRETE (RBC)
It is the combination of reinforcement, brick and concrete. It is well known fact that concrete is very weak in tension. Hence in the slabs, lintels and beams the concrete…
REINFORCED CEMENT CONCRETE (R.C.C.)
Concrete is good in resisting compression but is very weak in resisting tension. Hence reinforcement is provided in the concrete wherever tensile stress is expected. The best reinforcement is steel,…
Tests on Concrete
The following are some of the important tests conducted on concrete: 1. Slump test. 2. Compaction factor test. 3. Crushing strength test. 1. Slump Test: This test is conducted to…
Properties of Concrete
Concrete has completely different properties when it is the plastic stage and when hardened. Concrete in the plastic stage is also known as green concrete. The properties of green concrete…
CONCRETE
Plain concrete, commonly known as concrete, is an intimate mixture of binding material, fine aggregate, coarse aggregate and water. This can be easily moulded to desired shape and size before…
Wattle and daub
Wattle and daub, in building construction, method of constructing walls in which vertical wooden stakes, or wattles, are woven with horizontal twigs and branches, and then daubed with clay or mud. This method…
Tepee
Tepee, also spelled tipi, conical tent most common to the North American Plains Indians. Although a number of Native American groups used similar structures during the hunting season, only the Plains Indians adopted tepees as year-round…
