In reality, I think many people find it easy to identify risks to broad objectives; this can actually help us to then go back and more accurately identify specific objectives. For instance, a broad objective I might have is to survive. A risk to that survival is getting in a car wreck. So a more specific …
Soundness Test of Cement What is soundness of cement? The ability of cement to retain its volume after it gets hardened is known as Soundness of Cement. That means the cement should be at minimum volume change after it gets hardened. The test conducted to identify the excess amount of lime in cement is known as soundness test of cement.
Oct 01, 2016· Specific Gravity. The ratio of weight of oven dried aggregates maintained for 24 hours at a temperature of 100 to 110 0 C, to the weight of equal volume of water displaced by saturated dry surface aggregate is known as specific gravity of aggregates. Specific gravities are primarily of two types. Apparent specific gravity; Bulk specific gravity
