Used for finding specific gravity of Hydraulic Cement. Made from Borosil glass.
The flask is 243 mm in total height, having a bulb of 90 mm dia of 250 ml approximately capacity. The long neck of the flask has at top a funnel of 50 mm dia in which fits a ground glass stopper. The neck has over-all 11 mm I.D. upper portionis graduated from 18 ml to 24 ml with .1 ml graduation. Just at the bottom of the nek 1 ml capacity is marked in between there is 17 ml capacity bulb.

ZI-1010 GILLMORE NEEDLE APPARATUS ASTM-C 191

The instrument is used for determining the time setting of hydraullic cement.
Specifications : A base with a vertical shaft and two horizontal arms. The lower arm is adjustable for height 1 No. Initial Needle 1/12 inch dia 1/4 Ib.wt. 1No. Final Needle 1/12 inch dia. 1Ib.wt. 1No. Glass base plate. Complete as

ZI-1011 KELLEY BALL PENETRATION APPARATUS 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 faster than the slump test. Twice the Kelly Ball reading approximately equals the slump.
Specifications : It consists of a cylinder with a ball - shaped bottom and handle, together weighing 15 Kg. A strip frame, guides the handle and serves as a reference for measuring the depth of penetration. The handle is graduated in MM. Penetration can be recorded to the nearest 0.5 mm.

ZI-1012 SOUTHARD VISCOMETER IS : 6932 (Part - VI).

Lime putty consistancy can be adjusted using this instrument. A 50mm I.D. metal cylinder is mounted on a wooden platform. A closte fitting piston moces up and down without turning in this cylinder. Working strock is 65 mm. A metal bridge is provided to measure degree to which ejected

ZI-1013 VEE BEE CONSISTOMETER IS : 1199.

The instrument is used for workability as well as consistency of fresh concrete.
A slump cone and a graduated rod supplied with the instrument helps the operator to find out slump values and Vibration Table with container and acrylic disc is used to find out workability of concrete expressed in Vee Bee degrees, which is defined as the time in seconds to complete required vibrating at which the fresh concrete flows out sufficiently to cone in contract ot the entire face of acrylic disc.
Specifications : The equipment consists of : A Vibrating Table size 380 mm long and 260 mm wide, resting upon elastic support at a height of about 305 mm above the floor, complete with start/stop Switch, Cord and Plug. A holder is fixed to the base into which a swivel arm is telescoped with funnel and guide sleeve. The swivel arm is also detachable from the Vibrating Table. A graduated rod is fixed on a swivel arm and at its end a plastic disc is screwed. The divisions of scale on the rod record the slump of the concrete in millimeters. supplied complete with a sheet metal
container with lifting handles which can eZIIY be fixed to the Vibrating Table. A slump cone open at both ends with lifting handles and a Tamping rod of size 16 mm dia 600 mm long, rounded at one end.

ZI-1014 SLUMP TEST APPARATUS IS : 7320.

It is used for the determination of the consistency of freshly mixed concrete, where the maximum size of the aggregate does not exceed 38 mm.
Specifications : The apparatus consists of the one slump cone with handles and foot pieces. The Slump cone has internal diemesions 20 cm. dia at base 10 cm. top dia. and 30 cm. height. Foot pieces can be fixed to the clamps on the base plate. The base plate has lifting handle for easy transportation. One graduated steel rod 16 mm dia x 600 mm long, rounded at one end and graduated in mms, is also supplied.

ZI-1015 AIR ENTRAINMENT METER IS : 1199 - 1959.

As Entrainment of air in limited percentage inproves durability of concrete and very low percentages deteriorate it, measurement air entrapped in freshly mixed concrete becomes important. The use of chemical additices to increase workability of concrete otern requires an air content check to be made. Air Entrainment meters are used to determine air entrained in freshly mixed concrete by pressure method. Specifications : The apparatus consists of a pressure tight flanged cylindrical measuring bowl of 0.005 cubic mete capacity for maximum size of aggregate 38 mm.
The bowl is fitted with a removable flanged concial cover assembly with the help of a seal. The concial cover has an air valve and a pet cock for bleeding off the water. A transperent cylindrical stand pipe which is graducted in air content is fixed to the concial cover assembly.
Pressure is applied to the spicemen with the help of a pressure bulb and the pressure is recorded on the pressure gauge which is mounted on the stand pipe. The whole assembly is mounted on a flat base.
The instrument is supplied complete with one each following accessories. Calibration cylinder with spring clamp, Trowel, Tamping Rod, Straight edge, Rubber mallet and measure.

ZI-1016 AIR ENTRAINMENT METER

Same as above but 0.007 cubic meter capacity for maximum size of aggregate 38 mm.
