In a constantly evolving society there stems a need to develop and improve the current infrastructure. In order to build new infrastructure, building materials such as concrete will be needed. The raw materials needed for

Self-compacting Concrete: Fresh Properties

July 1, 2017 TeamCivil Concrete, Materials, Types

Self-compacting Concrete: Fresh Properties Self-compacting concrete has specific fresh state properties which conventional concrete does not have. Fresh concrete properties of SCC are obviously related to its property of self-compactability. Self-compactability in mechanism terms is

How to Prepare Cube Samples from Fresh Concrete?

June 24, 2017 TeamCivil Concrete, Tests

Most standards have laid down the acceptance criteria of quality concrete. In all the cases, the 28-days compressive strength shall alone be the criterion for acceptance or rejection of the concrete. 7 days compressive strength of

Concrete Admixtures

Nowadays concrete is being used for various purposes to make it suitable in different conditions. In these conditions ordinary concrete may fail to exhibit the required quality performance such as durability, strength, workability and finishing quality of concrete.

Reinforcement Steel and Prestressing Tendons

June 21, 2017 TeamCivil Concrete, Materials

Reinforcing Steel Because in prestressed concrete structures the role of primary reinforcement has largely been replaced by prestressing steel, an unfortunate tendency has been to denigrate the importance of supplementary conventional reinforcing. Conventional reinforcement fulfills

In this article, the three types of Alkali–Aggregate Reactions are described: (1) alkali–carbonate reaction (ACR), (2) alkali–silicate reaction, and (3) alkali–silica reaction (ASR). Alkali–Aggregate Reactions Water in the pores of hardened concrete contains quantities of dissolved ions

Concrete Distress Identification

June 13, 2017 TeamCivil Concrete, Durability, Repair

Distress Identification Before attempting any repair procedure it is necessary to have a planned approach to investigate the condition of concrete and reinforcement. While the diagnosis of damage or deterioration in some cases is reasonably
