What are Stirrups? A stirrup is a closed loop of reinforcement bar, which has a main function of holding the main reinforcement (RFT) bars together in a reinforced concrete element. Stirrups can come in multiple

What is Pervious Concrete? Pervious concrete is a structural concrete pavement with a large volume (15 to 35 percent) of interconnected voids. Similar to normal concrete, pervious concrete is made from a mixture of cement,

Flexural Strength Flexural strength is an indirect measure of the tensile strength of concrete. It is a measure of the maximum stress on the tension face of an unreinforced concrete beam or slab at the point

Effect of SCMs on Alkali-Silica-Reaction Mitigation 1- Fly Ash the three characteristics of fly ash that determine its efficiency in preventing ASR are fineness, mineralogy, and chemistry. In general, the finer the fly ash, the

Concrete Spalling Currently, there are two mechanisms concerning the occurrence of spalling: 1- the pore pressure build up causes spalling in the cement matrix and 2- thermal and mechanical stresses. In 1997, Anderberg gave an account

Corrosion of Embedded Metals in Concrete Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel.

Origin and Classification of Aggregates Most of the properties of an aggregate derive from its parental rock chemical and mineral composition which affects strength, stiffness, density, pore structure and permeability. Rocks experience geothermal and weathering

Pervious Concrete Pervious concrete is a type of concrete with a system of interconnected pores allowing water to rapidly drain through. Pervious concrete itself is made up of coarse aggregate that is coated by a
