Sample Preparation

Modern test procedures require specimens of cements, limes and related materials when formed into mortar, to be cast in certain standard shapes and sizes for determining the mechanical properties with a view to have a proper control on the quality of materials used. Mortar is prepared by mixing 185 g cement, 555 g standard sand and 74 g water separately for each cube of 70.6 mm. The homogeneous mixing is done using a mortar mixer and compacted using a vibration machine.

Mortar Mixer
IS: 10890-1984
This apparatus has specially been designed to prepare cement mortar for strength determination as specified in IS: 4031. It can also be used in mixing lime with pozzolonic materials for determination of lime reactivity (as per IS: 1727) and for uniform mixing of soils with additives such as lime, cement, etc. The stainless steel mixing bowl has a capacity of 4.75 litres. The paddle, also made of stainless steel, can have both planetary and revolving motion for uniform mixing. It can be electrically driven at two speeds:

Vibration Machine
IS: 4031
A specially designed Vibration Machine is used for vibrating the mix in moulds according to strictly controlled programmer at a frequency of 12,000 ± 400 cycles per minute. The Vibrator is mounted over coiled springs and the vibrations are developed by means of a revolving eccentric shaft. The center of gravity of the vibrator, including the cube and mould, is either at the center of the eccentric shaft or within 25 mm below it. The simple design of the machine facilitates easy assembly and dismantling of the cube moulds. The machine is suitable for operation on 230 V, 50 Hz, and single-phase, AC supply. Each machine is supplied with one cube mould.
The following mould can be ordered, as optional extra
Mould M. Steel, for 70.6 cm cube
