The compressive strength of the concrete reviewed in this study uses nanosilica and coconut fibers. The addition of coconut fibers to concrete contributes to the construction of sustainable and environmentally friendly building materials. The testing method carried out physically and mechanically. Testing the compressive strength of the nanoconcrete composite with variations in the amount of nanosilica which substituted with cement. Using variations of nanosilica composition, namely 0%, 0.5%, 1%, 1.5%, and 2% added with coconut fiber to determine the effect of compressive strength from nanoconcrete composite. The results obtained are the optimal value of concrete compressive strength with nanosilica is the addition of 2% nanosilica, which increases 43% of standard concrete. Moreover, on concrete with the addition of nanosilica and the addition of coconut fibers 1% test results in concrete compressive strength which is optimal in the addition of 0.5% nanosilica, which is 58% increase from normal concrete. The conclusion of this study that the addition of nanosilica and reinforced with coconut fiber will increase the compressive strength of concrete, this is an excellent composite material to get environmentally friendly building materials using.

81 concrete prism specimens under axial compression were tested to invesgigate the size effect on the axial load stength. Three different kinds of specimens with the dimension 100×100×300mm, 150×150×300mm, 200×200×400mm were tested. The parameters including compressive strength of concrete and aggregate composition are taken into consideration. Three different strength grades of concrete and three different aggregate composition are included in those specimens. The test method are undertaken according to ASTM C 39/C 39M-2005. Based on the test results, a new size effect law for different kinds of concrete in prismatical compressive strength is suggested and those relative parameters on the size effect are discussed.

Abstract: The composition of the concrete mixture determines the compressive strength. Concrete mixtures generally consist of cement, water, coarse aggregates, fine aggregates, and concrete drugs. In this study, it will be tried to mix stone ash and coconut fibers. The purpose of this study is to find out the concrete compressive strength with add stone ash and coconut fibers to normal concrete. Data was collected through laboratory tests by carrying out an additional mixture of stone ash and coconut fibers. There were six types of specimens produced which were measured for 7, 14, 21, and 28 days. Variation of specimens 1) normal concrete, 2) normal concrete + stone ash, 3) normal concrete + coconut fiber (1.5%), 4) normal concrete + stone ash and coconut fiber (1.5%), 5) normal concrete + stone ash and 1% coconut fiber, 6) normal concrete + 1% coconut fiber. From the results of testing the concrete compressive strength was obtained 455 kg/cm2 for the age of concrete for 28 days with a mixture of normal concrete + stone ash.

Quickcure CX is a chemical for concrete designed using the latest technological innovations, this added material can accelerate and increase the compressive strength of concrete by 5 - 10% and can reduce the moisture content in the concrete mixture by 5 - 10%. The purpose of this study was to increase and accelerate the effect of the compressive strength value of concrete produced by Quickcure CX added material on K-500 concrete.The research sample is a cube-shaped test object with a size of 15cmx15cmx15cm. There are 4 sample variations, namely: Normal Concrete, Normal Concrete + Quickcure cx 0.25%, Normal Concrete + Quickcure cx 0.45%, and Normal Concrete + Quickcure cx 0.65%, each variation consisting of 15 samples.After conducting the concrete compressive strength test, this study obtained the highest average compressive strength test results in Normal Concrete (503.2kg / cm2), Normal Concrete + Quickcure cx 0.25% (513.8kg / cm2), Normal Concrete + Quickcure 0.45% (536.4kg / cm2) and Normal Concrete + Quickcure cx 0.65% at 551.6kg / cm2 at the age of 28 days. So of the 4 variations in the value of the compressive strength test of concrete, it still increases in Normal Concrete + Quickcure cx 0.65%, and accelerating the concrete does not accelerate because the average age is 21 days with a variation of Normal Concrete + Quickcure cx 0.65% with a value of 488.8 kg / cm2 so the concrete has not reached the compressive strength that was planned.Keywords: Concrete, Quikcure CX, Compressive Strength, K-500

The aim of the research is to produce an environmentally friendly brick and also know the pressure and water absorption of the concrete- based concrete mixture of styrofoam waste, coconut fiber, and rubbing ash. The method used in this research is quantitative experimental research method. Based on the test results, it can be concluded that in order to achieve maximum pressure the composition of the waste should be 25% and to achieve the minimum absorption, the composition of the waste should be 50%. Batako with a waste composition of 25% and 50% can be categorized as suitable for use based on the results of compressive strength and water absorption. Meanwhile, concrete blocks with 75% waste are not suitable for use because the results of pressure testing are below the minimum standard SNI No. 03-0349 in 1989.

In this paper a case study about concrete strength assessment of bridge structure experiencing fire is discussed. Assessment methods include activities of visual inspection, concrete testing by Hammer Test, Ultrasonic Pulse Velocity Test, and Core Test. Then, test results are compared with the requirement of RSNI T-12-2004. Test results show that surface concrete at the location of fire deteriorates so that its quality is decreased into the category of Very Poor with ultrasonic pulse velocity ranges between 1,14 – 1,74 km/s. From test results also it can be known that concrete compressive strength of inner part of bridge pier ranges about 267 – 274 kg/cm2 and concrete compressive strength of beam and plate experiencing fire directly is about 173 kg/cm2 and 159 kg/cm2. It can be concluded that surface concrete strength at the location of fire does not meet the requirement of RSNI T-12-2004. So, repair on surface concrete of pier, beam, and plate at the location of fire is required.
