Accelerated Curing Tank having capacity to accommodate 6/12 specimen of Concrete Cubes of 150mm size with a facility for accelerated curing by Cooling and Boiling water method up to temperature range : 10C to 100 +/- 2 C as per IS standard IS : 9013.

Tank will consist of a rectangular double walled metal cabinet, inside lined with stainless steel, outer powder coated. Easily replaceable high Wattage heaters are mounted in side the chamber. A slow speed stirrer is provided to circulate water inside the chamber to maintain the uniform temperature of water. A strong stainless steel perforated platform is provided for keeping the cubes and also have a lid with lifting handle to cover the chamber.

The temperature is indicated and controlled by a DIGITAL auto tuning PID Temp. Controller with soak timer to control the duration of heating and then to shut down the system without manual attendance. The front panel will have power supply indicating lamp, control action indication lamp and one main switch. Suitable for operation on 220 V, 50 Hz single phase, AC supply or 440 V 50 Hz, three phase AC supply, for bigger size of curing tank.

It is used to measure the drying shrinkage of autoclaved Portland cement and potential expansive reactivity of Cement aggregate combinations in mortar bars during storage on self-drying.

The instrument consists of channeled base over which two vertical pillars are fixed. An adjustable cross plate is at the top. A dial gauge, reading to 0.002 mm x 12 mm or 0.01 X 25mm is fixed to the top. The plunger end of the dial Gauge can be located up on a 6.5 mm. dia ball or other reference point cemented in the specimen. On the base there is a similar recessed seating in which can be placed a second ball or reference point in the specimen.

Complete with a stainless steel standardization bar with insulated grip and with 6.5mm dia ball mounted in the ends.
