Steps for Waterproofing a Terrace or Balcony

Steps for Waterproofing a Terrace or Balcony

What is Waterproofing? A structure that allows moisture infiltration can experience serious damage. When water exists in liquid form, the impact on structure can be catastrophic, causing it to be uninhabitable. Waterproofing refers to the options that can prevent moisture penetration under hydrostatic head pressure.   Thus, waterproofing is an essential component for the durability during service …

Flexural Strength of Concrete

Flexural Strength of Concrete

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 of failure in bending. It is measured by loading 150 x 150-mm (or (100 x 100-mm) concrete beams with a span length …

Reasons of Concrete Spalling

Reasons of Concrete Spalling

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 on spalling caused by vapour pressure. The mechanism is believed to be the same for both High Performance Concrete (HPC) …
