Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall. This research was based on the performance of aerated lightweight concrete. However‚ sufficient water cement ratio is vital to produce adequate cohesion between cement and water. Insufficient water can cause lack of cohesion between particles‚ thus loss in strength of concrete. Likewise too much water can cause cement to run off aggreagate to form laitance layers‚ subsequently weakens in strength

one of the effects of consumption. Earthjustice says cement kilns are infecting our air‚ water‚ and food with mercury. Cement kilns release mercury into the environment through the cement-making process. Mercury is released in the air then goes to the water‚ which then infects the fish‚ which makes it unsafe for people to eat. In order to control mercury pollution‚ E.J. wants the Environmental Protection Agency to set mercury standards for cement kilns. E.J. Wrote a report called‚ “Cementing a Toxic

material due to its low cost and easy fabrication. Concrete is made up of sand or stone‚ known as aggregate‚ combined with cement paste to bind it. Aggregate can be of various sizes. It is broadly categorized as fine (commonly sand) and coarse (typically crushed stone or gravel). The greater proportion of concrete is aggregate which is bulky and relatively cheaper than the cement. As much of the constituents of concrete come from stone‚ it is often thought that concrete has the same qualities and
