Accelerated Curing Tank For Concrete Testing

Accelerated Curing Tank
Accelerated Curing tank shall be constructed from any material of suitable strength that will resist the effect of corrosion. Internal dimension should be adequate to accommodate the required number and size of test specimen. The tank shall contain sufficient water and be controlled so that temperature of water around the specimen immersed in the tank is maintained at the desired level.

EXPERIMENTAL PROGRAM-To get the early age strength through accelerated curing, warm water method was adopted. In this method, after the casting of cubes, specimen was cured at normal temperature for 24 hours and then put in accelerated tank on second day with temperature 80 for 5 hours and then 80c to falling temperature up to next day. After this period of curing, concrete cube specimen was tested for compressive strength and results are co-related with 28 and 56 days compressive strength of standard water curing. This co relation of accelerated strength and normal curing strength is achieved for all types of cement. To find the confident level of these relation seven different types of cement were used. The composition of different types of Cement is given in table IV. For each type of cement four different were used. Mix design was prepared by ACI method.
