Infrastructure development is one of the important aspects of the progress of a country where most of the constituents of infrastructure are concrete. The most important constituent of concrete is cement because its function is to bind other concrete materials so that it can form a hard mass. The large number of developments using cement as a building material will leave quite a lot of cement bags.In this study, the authors conducted research on the effect of adding cement waste to the compressive strength of concrete. This study used an experimental method with a total of 24 test objects. The test object is in the form of a concrete cylinder with a diameter of 15 cm and a height of 30 cm and uses variations in the composition of the addition of cement waste cement as a substitute for fine aggregate, namely 0%, 2%, 4% and 6%. K200). The compressive strength test was carried out at the age of 7 days and 28 days.The test results show that the use of waste as a partial substitute for fine aggregate results in a decrease in the compressive strength of each mixture. at the age of 7 days the variation of 2% is 16.84 MPa, 4% is 11.32 MPa and for a mixture of 6% is 6.68 MPa. Meanwhile, the compressive strength test value of 28 days old concrete in each mixture decreased by ± 6 MPa. So the conclusion is cement cement waste cannot be used as a substitute for fine aggregate in fc 16.6 (K200) quality concrete because the value is lower than the specified minimum of 16.6 MPa.

Improving technological advances, the use of concrete as a building is very popular in Indonesia. Because it can utilize locally available materias such as crushed stone, pebble, sand, cement and water at a relatively cheap price. In everyday use is often found in construction worker housing projects that use waste water (Water Sewer) for the construction of concrete. This certainly requires a closer examination toward the quality of concrete produced. The method of data analysis begins with a cement investigation, coarse and fine aggregate. Concrete mixing uses clean water (PDAM) as reference and waste water (Water Sewage) from Unisla rusunawa building. From result of analysis which have been done, concrete compressive strength test result at age 7, 14 and 28 days with mixing of clean water equal to 13,68 Mpa, 18,51 Mpa, 21,04 Mpa, while concrete test result at Age 7, 14 And 28 days with Water Sewage mixing of 9.99 MPa, 13.35 MPa and 15.36 MPa.Keywords : Waste Water, Concrete, Compressive Strength

Waste Tire Rubber

With the increasing number of vehicle due to the boom of population and rapid modernisation, the management of waste tire is growing problem. Reusing grinded tire rubber in concrete is a green innovation which provide an outlet for reusing waste tire. While providing certain benefits to concrete, incorporation of tire rubber results in significant loss of concrete compressive strength which hinders the potential of rubberised concrete. This paper aims to develop mathematical models on the influence of tire rubber replacement on the compressive strength of concrete using design of experiment (DoE). 33 data sets are gathered from available literature on concrete with waste tire rubber as partial replacement of fine aggregate. Response surface methodology (RSM) model of rubberised concrete compressive strength shows great accuracy with coefficient of determination (R2) of 0.9923 and root-mean-square error (RMSE) of 2.368. Regression analysis on the strength index of rubberised concrete shows that rubberised concrete strength loss can be expressed in an exponential function of percentage of replacement. The strength loss is attributed to morphology of rubber particles and the weak bonds between rubber particles and cement paste. Hence, tire rubber replacement should be done sparingly with proper treatment and control to minimise concrete strength loss.

Main Material

Concrete is one of the most vital building blocks, from columns, bricks, paving to roads made of concrete, so the use of concrete tends to be high. Concrete is often used as the main buffer in a building, so good quality is needed, but this is not accompanied by a declining quality of the material, so it requires innovation in the addition of new materials that can at least reduce the needs of the main material for making concrete, one of which is the utilization of Gypsum Board waste and red brick waste. The results of testing the concrete compressive strength test with the addition of Gypsum Board waste and red brick waste to cement obtained pretty good results. Concrete, which has the highest average compressive strength than normal concrete, has concrete with a mixture of red brick and gypsum waste of 10% each with a compressive strength of 250.56 kg / cm², and which has the lowest compressive strength have concrete with a mixture of red bricks and gypsum waste 15% each with a compressive strength of 195.56 kg / cm².Beton merupakan salah satu unsur penyusun bangunan paling vital mulai dari kolom,bata, paving hingga jalan terbuat dari beton sehingga penggunaan beton cenderung tinggi.
