The fineness of cement has a significant effect in its physical properties when used in concrete. Generally the finer the cement powder, the more rapid the concrete will set, as there is an increase in its surface area. The measure of fineness is usually undertaken by sieving, and the result assessed against the cement standard for compliance.

The Blaine air permeability apparatus is used to determine the fineness of Portland cement in terms of the specific surface expressed as total surface area in square centimeters per gram of cement. The Blaine apparatus draws a defined volume of air through a prepared bed of cement of defined porosity.

The apparatus comprises one each of Brass or stainless steel permeability cell 12.5mm, 'U' tube manometer with stop cock mounted on a laminated wooden stand, perforated metal disc, plunger, Rubber stopper, Rubber tube - 30cm long with rubber bulb.

• Balance with 0.001 gm resolution
• Stop Watch with 0.5 second resolution
• Manometer Liquid

Used to determine the amount of water required to produce a cement paste of standard consistency and the setting time. The time it takes for a cement to stiffen to a standard value after addition of water is commonly known as the set time. The test involves mixing cement with water and then measuring its resistance to penetration of a standard probe at varying intervals of time, until a certain value is reached.

A concrete structure is considered to be of adequate durability if it performs in accordance with its intended level of functionality and serviceability over an expected or predicted life cycle. Concrete durability depends largely on the ease (or difficulty) with which fluids (water, carbon dioxide, oxygen) in the form of liquid or gas can migrate through the hardened concrete mass. Concrete is a porous material. Therefore, moisture movement can occur by flow, diffusion, or sorption. We are concerned with all three, but generally the overall potential for moisture in concrete by these three modes is referred to as its permeability.

The set up consist of permeability cell, water reservoir and pressure lines, with glass bottles.

Consists of a metal cylinder with a ledge at the bottom for retaining the specimen, a flange at the top, removable cover plate and a funnel. A rubber gasket is seated in matching grooves, between the cell and the cover plate, to render the joint water tight. Internal working size of the cell will be 100mm dia X 100mm height.

Consists of a length of metal pipe, 50 to 100 mm in diameter and about 500 mm long. The reservoir fitted with a graduated side arm gauge-glass for admitting water and compressed air and a cock for drainage, bleeding and connection to the permeability cell.

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of the sample expressed a s a percentage is defined as Aggregate Crushing Value. The apparatus is available in three size 75mm dia for 1/8 to size aggregate, 150mm dia for 3/8 to aggregate (standard) and 300mm dia for 1 to 2 aggregate.

Consists of Case hardened Mild steel cylindrical container of 150mm dia+0.5mm x 130mm to 140mm high with base plate 200 to 230mm square x 6mm thick. A plunger of 148mm+0.5mm dia x 100 to 115mm high. All parts directly coming in to contact with the specimen during the test are made of mild steel duly case hardened. Supplied complete with tamping rod, 16mm dia x 600mm long, one end rounded.
