ACI Concrete Terminology

air entrainment — the incorporation of air in the form of microscopic bubbles (typically smaller than 1 mm [0.04 in.]) during the mixing of either concrete or mortar. (See also air entraining and entrained air.) air lift — equipment whereby slurry or dry powder is lifted through pipes by means of compressed air. air meter — a device for

Precast Concrete - What is Precast Concrete? - Concrete

22/6/2020· Dry-cast concrete is very dry (w/c of 0.30 to 0.36), has zero slump, and the forms can be stripped as soon as the concrete has been consolidated. Dry-casting requires an expensive dry-casting machine and is typically used for mass production of products like concrete pipe or manholes and also in concrete block production.

Bulk Modulus - an overview | ScienceDirect Topics

Bulk modulus is the measure of the decrease in volume with an increase in pressure. The “modulus of elasticity” of a liquid varies widely, depending on the specific gravity and temperature of the liquid. Typical values are less than 30,000 psi to greater than 300,000 psi, depending upon the liquid. Pipe containing liquid has an ability to

1926.702 - Requirements for equipment and tools

Concrete pumping systems using discharge pipes shall be provided with pipe supports designed for 100 percent overload. 1926.702(e)(2) Compressed air hoses used on concrete pumping system shall be provided with positive fail-safe joint connectors to prevent separation of sections when pressurized.

Explained: Cement vs. concrete — their differences, and

3/4/2020· Carbonation occurs gradually in concrete as CO 2 in the air reacts with cement to form water and calcium carbonate. A 2016 paper in Nature Geoscience found that since 1930, carbonation in concrete has offset 43 percent of the emissions from the chemical transformation of calcium carbonate to clinker during cement production.

ConCrete Sampling and teSting - National Precast Concrete

the concrete contains an air-entraining admixture, these bubbles remain stabilized in the mix due to the electrostatic binding of air, water and cement. In concrete without air entrainment, all but about 2% of the air content escapes or dissolves after consolidation TeSTing.

Example 1: The bulk modulus of elasticity of air is 1.41x10 5 N/m 2 and its mass density is 1.29kg/m 3. Calculate the speed of sound waves in air. Solution: Using v = (B/ρ) 0.5, we get: v = [1.41x10 5 /1.29] 0.5 m/s = 331m/s. Example 2: The bulk modulus of elasticity of water is 2.1x10 9 N/m 2 and its mass density is 1000 kg/m 3.
