Literature Review Of Self-Curing Concrete

1614 Words7 Pages

Chapter 6 : Literature Reviews
Wen-Chen Jau gives statement that self-curing concrete will be provided to absorb water from moisture from air to attain better hydration of cement in concrete. It resolves the difficulty occurred when the degree of cement hydration is lowered due to improper curing by using a self- curing agent like poly-acrylic acid, which has strong capability of absorbing moisture from the atmosphere and providing water required for curing concrete.
M.V.Jagannadha Kumar,M.Srikanth, Dr.K.JagannadhaRao in their research studied that the optimum dosage of PEG400 for maximum strengths such as compressive, tensile and modulus of rupture was found to be 1% for M20 and 0.5% for M40 grades of concrete. As percentage of PEG400 increased, slump will also increased for both M20 and M40 grades of concrete. Strength of self-curing concrete will be on par with conventional concrete. Self-curing concrete will be the answer to many difficulties or problems faced due to lack of proper curing.
A.AielsteinRozario, Dr.C.Freeda Christy, M.HannahAngelin stated that the permeability of concrete will decreases with the increase in the replacement of fly ash with cement and in addition of PEG dosages. So the entry of chemicals will decreases with the addition or inclusion of PEG in the mixture and the concrete will be safe against sulphate. The percentage of weight loss of the concrete specimens is also decreased for every grades of concrete. From the results, we know that the

    Discussion In the Chemical Weathering Lab experiment, 4 different rocks were tested in 4 different substances, being 50% vinegar, 10% vinegar, soda, and distilled water. The mass of the rocks and the pH of the substances were both measured before the experiment began. The rocks were left for 5 weeks and the changes in mass and pH were observed. The reasoning for this experiment was to see how weathering would affect rocks, specifically chemical weathering.

    Introduction The Romans developed many architectural advances such as concrete and the arch. According to the University of California, Santa Barbara ( n,d) roman concrete is similar to modern concrete in that it is an artificial building material composed of an aggregate, a binding agent, and water. Roman contribution to this basic structural mixture (concrete) was the addition as primary binding agent pozzolona, a special volcanic dust found in central Italy. Pozzolona created an exceptionally strong bond with the aggregate.

    Sealcoating is a highly effective and economical way to help achieve the longest life possible for your asphalt pavement. Sealcoating acts as a barrier against potentially damaging elements, including UV rays, automotive fluids and deicing chemicals. In addition, sealcoating refreshes the color and improves the appearance of asphalt pavement. However, although there are some parts of the country in which sealcoating can be applied during virtually any month, in Central Kentucky, this is not the case. Most sealcoating jobs are performed between May 1 and September 30, but the month of May is actually the perfect time for sealcoating in this area.

    Discussion This lab was performed to show the effects of chemical weathering on rocks of the same size and composition by placing each one in a different solution. It was hypothesized that the 50% vinegar solution would cause the greatest amount of chemical weathering and that the 10% vinegar solution would cause less chemical weathering than the 50% vinegar solution. It was also hypothesized that the soda water would cause less chemical weathering than the 10% and 50% vinegar solutions and that the distilled water would cause the least amount of chemical weathering. Each hypothesis was formed based on the pH level of each solution. When rocks are exposed to acid in water, the water reacts with the minerals in the rock, speeding up the erosion of the rock (Aaron, 2018).

    Concrete is the primary material in construction industry. It consists of cement, coarse aggregate, fine aggregate, water and other admixtures. Generally Ordinary Portland cement is used in concreting but the production of OPC causes a huge amount of carbon emission and also it uses a huge amount of non-renewable natural resources. The concrete construction practice in use is considered as unsustainable because it consumes a huge quantity of sand, stone and water and 2.5 billion tons of OPC per year.
