The primary purpose of entraining air in concrete is to give the required resistance to weathering. The use of chemical additives to increase the workability of concrete often requires an air content check to be made.Precision Air Entrainment MeterThe proper control of entrained air in concrete is recognised as one of the most important functions in modern concrete manufacture.

The object of mixing is to coat the surface of all aggregate particles with cement paste, and bring the mix to a uniform condition. Pan or rotating drum mixers are suitable for the mixing of small quantities of concrete, which are generally used in a laboratory.Tilting Drum Concrete Mixer 120/90 Litre/ (4/3 cu.ft.)

The ELE Concrete Mixer is ideally suited for this purpose. The mixer has been developed to give efficient mixing of both wet and dry materials. The mixing pan is removable and tilts for easy access to the pan and emptying on completion of the mixing operation. It is rotated by a turntable driven by a 1500 W, IP55 protected electric motor.The mixer head lifts clear to provide maximum access to the pan and holds the mixing blades at a constant depth during the mixing operation. The blades are readily adjusted to suit the different types and volume of materials to be mixed. ±Portable and compact. ±Tipping mechanism. ±Adjustable blades. ±Simple to clean and maintain.

An increasing number of contract specifications call for various forms of vibro-compacted concrete as a means to achieve a better and more consistent mixture. It should however be remembered that fluid mixes may segregate when vibrated, in which case it may be more appropriate to compact using a tamping bar or rod during laboratory mix design.Vibrating PokerProduct Code: 34-6431/01Product Standards:EN 12390-2, ASTM C31/C31M, ASTM C192/C192M, AASHTO T23, AASHTO T126Used as an internal means of vibratory compaction. The poker is inserted into the concrete which is then compacted by the high frequency vibration action. For use in either laboratory or site environments, the diameter of the vibrating tip must not exceed 25% of the smallest dimension of the specimen. ±High amplitude and speed. ±Flexible shaft for long life.

Two primary factors must be taken into consideration to satisfy the requirements, namely to maintain a stable temperature and to prevent loss of moisture from the specimen. A standard curing temperature of 20°C is usually specified and should be maintained at the required degree of accuracy. The use of water to prevent loss of moisture is the method most commonly used. In tropical climates a curing temperature of 25°C is often acceptable.Large Curing Tank complete with Circulating Pump Heater/Thermostat Unit & Lower RackProduct Code: 34-6575/01This large curing tank is supplied complete with a submersible pump, immersion heater/thermostat unit and separate control panel.

Hardened concrete density is determined either by simple dimensional checks, followed by weighing and calculation, or by weight in air/water buoyancy methods.Hardened Concrete - Buoyancy BalanceThe density of hardened concrete specimens such as cubes and cylinders can be quickly and accurately determined using a Buoyancy Balance. The Buoyancy Balance system developed by ELE consists of a rigid support frame, incorporating a water tank mounted on a platform. The water tank has internal dimensions of 380 x 240 x 280 mm (L x W x H). A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. The balance supplied calculates the specific gravity of the sample automatically. The balance may also be used as a standard weighing device, thus providing a versatile and comprehensive weighing system in the laboratory.Buoyancy BalanceProduct Code: 34-8100/09 Product Standards:EN 12390-7 (BS 1881-114)SpecificationsPower Supply110-240 V AC, 50-60 Hz, 1 phDimensions L x W x H (mm)600 x 400 x 1000Weight (kg)32Spares/Consumables:Lifting Frame (34-8100/10)CradleProduct Code: 34-8105Product Standards:EN 12390-7 (BS 1881-114)SpecificationsDimensionsL x W x H (mm)210 x 140 x 280Weight (lbs)1.5Bulk Density Measures (Various Sizes)Product Standards:EN 1097-3Manufactured from heavy gauge steel these bulk density measures comply with the requirements of EN 1097-3.
