Concrete structures deteriorate with time despite the fact that concrete is inherently a durable material. This is because the concretes durability, under any given set of exposure conditions, varies with the concrete mixture proportions the presence and positioning of reinforcement and the detailing, placing, finishing, curing, and ...
It is always desirable to use the best cement in constructions. Therefore, the properties of a cement must be investigated. Although desirable cement properties may vary depending on the type of construction, generally a good cement possesses following properties which depend upon its composition, thoroughness of burning and fineness of grinding. ...

Mar 25, 2015nbsp018332Causes of Cracks in Concrete and its Remedies Cracks in concrete are caused due to following factors. One of the main causes of cracks in concrete is the cooling and contraction due to setting of concrete. Volume change and stresses due to shrinkage are independent of any external load or stress applied. Cracks may develop
Concrete with a pore solution of pH 10-12 is less alkaline than sound concrete but would still produce a strong color change with phenolphthalein indicator. It therefore follows that the indicator test is likely to underestimate the depth to which carbonation has occurred.
Jun 18, 2014nbsp018332In the early 1900s, cement fineness was expressed as the mass of cement per fractional size percent weight retained on specific sieve sizes. Now a days fineness is usually measured by the Blaine air-permeability test that indirectly measures the surface area of the cement
Aug 05, 2015nbsp0183325. Water Absorption Test. Here is the other test that would determine the durability of concrete. The three cube sample shall be taken from the delivered fresh concrete and kept it in the curing tank for 28 days or after 24 hours the concrete sample would be demoulded and it will be sent directly to the approved third-party laboratory to ensure its curing.

Nov 19, 2018nbsp018332And a power on test is ready for this unit. Before turning on it was found that the physical 0 of the bias knob and the static zero of the meter needed adjustment. The power line adjust test is done as part of the smoke test through the Variac. The smoke test looks good, and the basic turn on operation seems to be good to proceed.
1.1 This test method covers a procedure for evaluating the pull-off strength commonly referred to as adhesion of a coating system from metal substrates. Pull-off strength of coatings from concrete is described in Test Method D7234.This test offers two test protocols. Protocol 1 test to fracture determines the greatest perpendicular force in tension that a surface area can bear before a ...
concrete exposed to cycles of freezing and thawing Fig. 6-2. Entrained air greatly improves concretes resistance to surface scaling caused by chemical deicers Fig. 6-3. Fur-thermore, the workability of fresh concrete is improved significantly, and segregation and bleeding are reduced or eliminated. Air-entrained concrete contains minute ...
