Geopolymer concrete, or green concrete, is part of a movement to create construction materials that have a reduced impact on the environment. It is made from a combination of an inorganic polymer and 25 to 100 percent industrial waste. Here is a list of 4 benefits to using green concrete for your next project. 1. … Read more
An engineer who is instructed to investigate and report on a deteriorated concrete structure, and to prepare recommendations for necessary remedial work, should be clear in his own mind on the extent of this responsibilities to his client. If he is responsible for the inspection of the remedial work to ensure that the requirements of … Read more
Hydraulic cement concrete overlays are used as a rehabilitation technique for both existing concrete and asphalt pavements. Concrete overlays offer the potential for extended service life, increased structural capacity, reduced maintenance requirements, and lower life-cycle costs when compared with hot-mix asphalt overlay alternatives. Concrete overlays have been used to rehabilitate existing concrete pavements since 1913 … Read more
The effects of natural aggregates on the properties of concrete Concrete is defined as a workable mixture of a cementations material mostly cement mixed in suitable proportion with fine and coarser aggregate along with water. Concrete depending upon reinforcement is of two types, plain cement concrete (P.C.C) and reinforced concrete (R.C.C). Download Advanced Concrete Technology … Read more
@import url(http://fonts.googleapis.com/css?family=Oswald:700); The limit of water absorption by coarse aggregates is determined so as to calculate the appropriate amount of water to be added to the concrete mix, thus modifying the water cement ratio. A bone dry aggregate would necessitate, while for wet aggregate water contents should be reduced. \”Determine the water absorption by coarse … Read more
