Choose from a selection of hydrostatic test pumps from Grainger. They are suitable for testing residential water lines, small pressure tanks, sprinklers and boilers. Hand operated hydrostatic test pumps are designed to generate calibration pressures of up to 10,000 psi.
Sep 29, 2019· How to Read Syringes. You may think all you've got to do to read a syringe is look at the lines on the tube. But different syringes measure volume in different increments, and sometimes they don't use the standard unit, milliliters (mL)....
Aug 11, 2018· Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through sieve, the aggregate retained is called coarse aggregate.
May 28, 2014· Dcracking in a concrete slab is a progressive structural deterioration of the concrete beginning in certain types of susceptible coarse aggregate, caused by repeated freezing and thawing after absorbing moisture. The problem, which is more significant in larger sized particles, starts well out of sight at the base of the slab near the joints.

The primary purpose of the California Bearing Ratio test is to determine the bearing capacity and the mechanical strenght of road subbases and subgrades. In this test in the laboratrory, the sample is prepared at at Proctor's maximum dry density or any other density at which the test is required.
Apr 12, 2018· Use the fine aggregate for concrete slabs or other smooth surfaces. A "coarse" aggregate means using larger pieces of gravel. Coarse concrete is helpful for sturdier projects. Concrete with a coarse aggregate doesn't produce a smooth look or feel but is stronger than a finer grade.
