March 7, 2021 TeamCivil Concrete, Properties

Concrete Workability Concrete Workability is a property of concrete in its fresh state during mixing. It determines the ease with with casting activities are done including mixing, placing, compacting and finishing. Concrete workability is usually

Features of Sulfuric Acid Attack

March 4, 2021 TeamCivil Concrete, Durability

Sulfuric Acid Attack Sulfuric acid [H2(SO4)] attack on concrete may be identified by a chemical reaction between the acidic media and cement hydration products, leading to excessive formation of gypsum. Acid attack can occur under

Basic Types of Stirrups for Concrete Work

September 29, 2020 TeamCivil Concrete

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

Pervious Concrete: What Is It and Is It More Expensive?

September 28, 2020 TeamCivil Concrete, Types

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 of Concrete

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

Reasons of Concrete Spalling

January 25, 2019 TeamCivil Concrete, Durability

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

October 3, 2018 TeamCivil Concrete, Durability

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.
