Cement / Concrete Testing Instruments

AsPerASTMc-191
Gillmore Needle Apparatus: This instrument is used for determining the time setting of hydraulic cement. A base with a Vertical shaft and Two horizontal arms. The lower arms is adjustable for height. 1 no. Initial needle 1/12-inch dia 14 lb. Wt.1 no. Final needle 1/24 inch dia. 14 lb. Wt. 1 no. Glass base plate. Complete as above.

As Per ASTM C - 360
The apparatus is used to determine the workability of Portland cement concrete. The Kelly Ball test is considered to be simple and much fasterthan the slump test. Twice the Kelly Ball reading approximately equals the slump.

Concrete mixer laboratory type, electrically operated. Designed to remove the burden- some work of hand mixing. Uniform \£ thoroughly mixed batches can be produced. The counter balanced drum is easy to tilt 1.1/2 to 2cu.ft.mix. The total drum volume is however 3cu.ft. Mounted on a sturdy rubbertyred stand, and the drum is mounted for end discharge and equipped with end towing pole. Equipped with Vfc.p. electric motor. Suitable for operation on 220/230 volts A.C. single phase.

This is for determining the lateral extension of 15cms dia x 30cm high cement concrete cylinders while testing them under compression.

As Per IS : 1199-1959 & 4031-1968
Length Comparator: It Is used to measure the dying shrinkage of concrete autoclave expansion of Portland cement and potential expansive reactivity of cement aggregate combinations in mortar bars during storage, on self drying.
