Effect of temperature of fresh concrete on workability …

when the temperature of concrete is high than concrete tends to set fast which will affect the slump of concrete over the period i.e slump or workability of concrete will decrease over the period. this is because the high temperature increases the heat of hydration process of cement due to which concrete workability decreases.

Guide To Concrete Workability | Concrete Slump | …

One of the basic attributes of any concrete is its workability or "consistence", that is, how easy it is to push one way, pull the other, and float to a smooth level surface. Workability is largely determined by how fluid the concrete is. This is referred to as "Slump".

Effect of Temperature on Workability of Concrete

 · Concrete samples are generally tested in laboratory under controlled temperature and normally kept constant. Numerous tests were performed to set different standard and were conducted in temperate climates; so the temperature range of (18~21) 0 C were taken standard temperature.

Concrete Slump Test for Workability -Procedure and Results

The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. The slump is carried out as per procedures mentioned in ASTM C143 in the United States, IS: 1199 – 1959 in India and EN 12350-2 in Europe. ...

Workability, Setting Time and Strength of High-Strength …

Workability is one of the significant characteristics of high-strength concrete because such concrete is produced using a low water-cementitious ratio. Thus, extensive utilization of high range water reducer is necessary in order to attain the required rheological characteristics to facilitate mixing, transporting, placing and compacting.

The workability of the concrete was studied by conducting slump and flow tests as per the standard procedure 10 (Fig.3 and Fig.4). Standard cube specimens of 150mm x 150mm x 150mm size were cast using the procedure described in IS 516 code 11 and were immediately covered with plastic sheet and kept there for 24 hours and then released in water tank for 28 days curing.
