Air content of the freshly mixed concrete can be measured by gravimetric, volumetric, or pressure methods. The pressure method is the most commonly used, and in this method a calibrated air meter is used to test a known volume of concrete that is subjected to a defined pressure. Slump and Concrete Strength of Air Entrained Concrete
Air-entrained concrete is typically specified in areas of the country where frost-related damage can occur. The measurement of air content in fresh concrete of normal density is typically performed using the pressure method . Another useful test is ASTM C 173. However, the pressure method is frequently preferred because it is relatively fast.
The ROLL-A-METER is a simple device for measuring entrained air in freshly prepared concrete by using the rolling or washout method. The meter is for use with any type of aggregate (dense, cellular, or lightweight) not exceeding 2". The capacity of the meter is 130 cu. in. in the base section.
Foam concrete (FC) has the potential of being an alternative to ordinary concrete, as it reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the cost of production and labor cost during the construction and transportation. The paper reports a state-of-the-art review of foam concrete in terms of its components, manufacturing and material properties ...

Dec 09, 2014 · Air-Enterained Concret test by Volumetric Air Meter:This device measures air entrainment by the "Volumetric Method." Air is removed from a known volume of concrete by agitation in an excess of water. It may be used with any type of aggregate including light weight and porous material.

The test method equalizes a known volume of air in the pressure chamber, with the unknown value of entrained air in the meter’s concrete filled base. The amount of entrained air is then read on the meter’s gauge as the direct percentage of air entrained in the sample. Constructed of cast aluminum, the meter is durable yet lightweight.
Air Meter Concrete Testers Press-Ur-Meter—ML-2786 The original Press-Ur-Meter for field and laboratory tests, 1/4-cu.-ft. (.007m[sup]3[/sup]) air meter is designed to determine air content, determination of specific gravity and free moisture test of aggregates.
PRESCRIPTIVE MIXTURE DESIGN OF SELF-CONSOLIDATING CONCRETE The research investigation presented herein was intended to study the influence of parameters such as aggregate size, admixture source, hauling time, temperature and pumping on the fresh and hardened properties of three distinct groups of self-
Application: Concrete Mix Air Entrainment Meter is Widely used in construction work, road, rail, water utilities, ports. Airport construction and other construction site, the determination of air content of concrete, engineering quality supervision and management, research and teaching of concrete experiments.
The air indicator is designed to read directly for a concrete mix having 15 cubic feet of mortar per cubic yard (0.56 cubic meters of mortar per cubic meter) of concrete. Therefore, the air content as determined by each test must be corrected for mixes with a different mortar content.
Quality Concrete & Cement testing Instruments manufacturers & exporter - buy Concrete air entrainment meter, Air pressure gauge for concrete test from China manufacturer.
Small variations in specific gravity or large variations in mix proportions can again cause relatively large errors in air content. The volumetric test requires diluting the concrete with water, then repeatedly rolling and agitating the volumetric air meter to free the entrained and entrapped air.

21.5 Mix design for air-entrained concrete 21.5.1 Effect of air entrainers. Air entrained mixes are produced with the addition of an air entraining admixture, and are normally used to prevent freeze–thaw damage. The air entrainer will improve the workability and reduce the strength and the density (see Section 24.4). 21.5.2 UK practice
The only ingredient in the concrete that is compressible is the air. Cementitious material, water, and aggregates do not respond to the small rise in pressure. So the pressure change is correlated to the air content of the concrete. Entrained air is formed in concrete using a surfactant. The smaller the bubble, the stronger the bubble.
“Your predicament brings up a few questions; however, the answer is the same as for standard concrete. Mixing an air entrained mix with a non-air entrained mix will lead to a reduced air entrainment effectiveness. You did not mention the circumstances that led to this “mix mixing.”
Air entrainment is the intentional creation of tiny air bubbles in concrete. A concrete maker introduces the bubbles by adding to the mix an air entraining agent, a surfactant (surface-active substance, a type of chemical that includes detergents). The air bubbles are created during mixing of the plastic (easy flowing, not hardened) concrete ...
Another unique truck that Meter Mix and Forest City Redi Mix have available is the Front Discharge Truck. These trucks will hold 9 cubic metres of ready mix concrete the same as the other barrel trucks. The difference as seen, is the barrel is place on the truck backwards.
