Abstract

Concrete quality depends on the value of the ratio of materials, how to blend and how to pour the concrete mixture, how to compact and how to care for it during the hardening process. This study aims to determine how much influence the curing process using water with a mixture of Co(NH2)2 and normal water has on the compressive strength of concrete fc' 20 Mpa. The sample is a cylindrical specimen with a diameter of 15 cm and a height of 30 cm. Samples were made 3 test objects with the age of 28 days and tested coherently. The compressive strength of normal concrete has increased in quality with the age between 7 is 9.1 Mpa to 28 days is 17 Mpa. While the concrete with curring process using water with a mixture of urea increased at age 7 with a value of 10.8 Mpa to 21 days with a value of 14.4 Mpa, but at age 28 the strength of the concrete decreased by 12 Mpa. Cracks with cone and split types are 10 pieces, this can happen because the material in the concrete mixer has not been mixed well during the concrete manufacturing process.

Abstract

Concrete is a form of construction in the form of a composite material consisting of a mixture of fine aggregate, coarse aggregate, cement, and water. However, in certain cases, the concrete application is often a problem, especially the lack of a minimal amount of coarse aggregate material, increasing material prices. Recycled concrete aggregate (RCA) is an embodiment of concrete composed of recycled materials. Recycled material is obtained from fragments or remnants of the demolition of unused concrete. The method used to make concrete from the constituent materials using concrete waste as coarse aggregate per the rules of science is experimental. The tests are the aggregate moisture content test, the mud content test, the coarse aggregate abrasion test, the slump test, and the concrete compressive strength test at 28 days of treatment. The compressive strength results showed that the normal concrete sample could reach FC 18.53 MPa. The concrete sample using recycled coarse aggregate reached FC 23.79 MPa, so using recycled materials for manufacturing concrete can achieve the planned target

Abstract

The existence of construction projects has been considered a major source of environmental problems worldwide. However, basically the construction industry activities can make a positive contribution, this can be achieved if the whole process is carried out by taking into account the principles of sustainable development.To achieve a sustainable construction project requires a method that is effective and acceptable to all parties. Based on these problems, this study examines the integration of risk analysts to achieve sustainable construction using the literature review method.The results of this study indicate that there are 5 variables that affect the achievement of sustainable construction, namely social, environmental, economic, disaster and technical. The 5 variables are fully integrated in 2 forms of relationship, namely reinforcing and balancing, where these variables can strengthen each other, weaken each other and also balance each other. So that these variables can be integrated to achieve sustainable construction, some previous research results state that this can be achieved by risk analysis
