CEMENT CONCRETE MIX DESIGN - Dronacharya
www.gn.dronacharya.infoThe durability of concrete is its resistance to the aggressive environmental conditions. High strength concrete is generally more durable than low strength concrete. In the situations when the high strength is not necessary but the conditions of exposure are such that high durability is vital, the durability requirement will determine the water-

Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance. Figure 2 shows the effect of high temperature on the modulus of elasticity of concrete. The

FLEXURAL STRENGTH – A MEASURE TO CONTROL …
www.ijser.orgAbstract- Flexural strength is a measure of the tensile strength of an unreinforced concrete beam or slab to resist failure in bending. It is useful in knowing the quality of concrete work done in road construction.
Cracks and Crack Control in Concrete Structures
www.pci.orgConcrete cracks when the tensile strain, €°t, ex-ceeds 0.010 to 0.012 percent. This limiting tensile strain is essentially in-dependent of concrete strength. The 5 percentile of the tensile strength, f, should be used in design to locate areas in the structure that are likely to crack by comparing calculated stresses with the expected ...
