Asphalt and concrete pavements can be cost-effectively removed with cold milling machines. The range of applications extends from the complete removal of asphalt and concrete to the layer-by-layer removal and levelling of asphalt and concrete surfaces. With WIRTGEN cold milling machines, it is possible to machine working widths from 35 cm up to ...
Floor screeds
Floor screeds. A floor screed is usually a cementitious material made from a 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.
PRECAST CONCRETE MANHOLES
s = unit compressive stress in the ring (pounds per square foot) H = depth of manhole, feet Using an allowable concrete stress of 45% of the minimum specified compressive strength of 4,000 psi, the allowable compressive stress would be 1,800 psi. Substituting this value for s yields the following: = 3.4 s H 1,800 = 3.4H then H = 530 feet

Modulus of Elasticity of Concrete - Civil Engineering
Units of elastic modulus are followings: In SI unit MPa or N/mm 2 or KN per square meter. In FPS unit psi or ksi or psf or ksf. Modulus of Elasticity of Concrete. Modulus of Elasticity of Concrete can be defined as the slope of the line drawn from stress of zero to a compressive stress of 0.45f' c. As concrete is a heterogeneous material.
Flat Jacks | Controls Group
The test is performed by making a cut to a uniform depth into the mortar courses and inserting the flat jack or couple of jacks, which are pressurized to the desired level. For stress determination a single flat jack has to be used. For deformability and resistance determination two flat jacks have to be used. 58-D0568/A Hydraulic pump with gauge.
Density (Unit weight) of Concrete - Bulk Density - Civil ...
If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. lb/ft 3 is also used as pcf. In this definition, the volume is that contains both the concrete and the voids between concrete particles. Here, the Standard test method for determining the bulk density of concrete is given in ASTM C138 / C138M (AASHTO T 121M/T 121). [1]
Calculators - Lehigh Hanson
Strength – Most concrete is ordered with a performance compressive strength at a 28-day measure of a hardened concrete cylinder. We have information on our website for typical application specifications and proper testing procedures. Any slab exposed to freeze-thaw conditions should be a minimum of 4,000 psi with air entrainment.

GEN 3 Concrete | C20 Concrete | The Concrete Network
One of the most common lightweight mixes we deal with is GEN 3 / C20 concrete. With a strength rating of 20 newtons after 28 days, this mix is commonly used for domestic projects, but can also be used for certain commercial applications. As a lightweight mix, GEN 3 / C20 concrete has the highest cement content of all other individual GEN mixes.

mix ratios for c10 c15 c20 c25 c30 grade concrete by volume
There are different concrete grades for example C15, C20, C25. The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C15 means that the concrete will have a compresion resistance (withstanding a compression) of 15 N/mm2 per square millimetre in 28 days.
