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

Perumpung (Eulalia japonica) is a wild plant that usually grows on the banks of river. The locals consider this plant as a waste/pest, but the authors are interested in researching perumpung because they are similar to bamboo, sugarcane and other fibrous plants. In this study, the authors aims to compare the compressive strength of normal concrete with the compressive strength of concrete added with Perumpung ash at 28-days-old K-300. The study used a cube-shaped test object (15 x 15 x 15 cm) with 6 samples for each condition. The total number of test objects is 48, which consists of 8 conditions, namely normal conditions and 5%, 7.5%, 10%, 12.5%, 15%, 17.5% and 20% addition of perumpung ash by cement weight. The results obtained that the compressive strength of 28-days-old concrete under normal conditions was 316,060 kg/cm2 and the addition of 5% ash was 331.583 kg/cm2, 7.5% was 337.181 kg/cm2, 10% was 341.813 kg/cm2, 12 ,5% is 347,045 kg/cm2, 15% is 353,889 kg/cm2, 17.5% is 311,160 kg/cm2 and 20% is 298.44 kg/cm2. From the results above it can be concluded that the addition of 15% Perumpung Ash to the concrete mixture increases the maximum characteristic concrete compressive strength by 353.889 kg/cm2.

This paper concentrates on preparing concrete in which reverse osmosis waste water is incorporated in mixing and to cure. Experimental procedure consists of 4 mix proportions of various water cement ratios. Fresh concrete is tested for workability and flowing ability. Cubes were casted and tested to find out compressive strength of concrete. Test results of potable water concrete and RO waste water concrete were compared. Results show that workability of both the concretes is almost same. When coming to the compressive strength, RO waste water concrete shows less strength at 28days compared to normal concrete.

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.

The more widespread use of concrete construction and the increasing scale of construction, the higher the demand for materials used in concrete mixes. One of the innovations of concrete is fiber concrete. Hope the addition of fiber in concrete mixes such as wire fiber to increase the compressive strength value of normal concrete that is often used, so the purpose of this study is to determine the effect of adding wire fiber to the ease of working (workability) of the concrete mixture and to determine the effect of adding wire fiber to concrete compressive strength. In this study, the fiber used is the type of wire fiber with a diameter of 1 mm and a length of 60 mm. Fiber variations used are 0%, 0.4%, 0.6% and 0.8% based on the weight of fresh concrete. Concrete mix (mix design) using SNI 03-2834-2000 about concrete mix planning with a test life of 28 days. The test results showed that the lowest average compressive strength of 12,291 MPa occurred at 0% variation and the highest average compressive strength value of 20,656 MPa at 0.8% fiber variation. The increase is caused by the even distribution of fibers in the concrete produced, the higher the variation that is given by the fiber, the better the fiber spread, from these fibers provide a fairly good contribution to the fiber concrete

Abstrac This research was conducted to determine the effect of the addition of waste shells and shell powder glass powder on the compressive strength of concrete. The method used is to use the experimental method by making test specimens with a mixture of waste shells powder shells and glass powder by 4%; 8%; 12% then compared with normal concrete without added ingredients. Concrete specimens that have been soaked then tested their compressive strength with the age of 7 days, 14 days, 21 days, and 28 days. The results of the test showed that normal concrete which was not added with the waste of shell powder and glass powder had compressive strength under mixed concrete variations of 4%, 8%, and 12 % when the concrete was 28 days old. Concrete which is added with waste of shell powder and glass powder has  a high yield at 4% variation that is equal to 20,66 MPa. For concrete Variasi of 8% has a compressive streng value of 20,17 MPa, For variations of 12% has a compressive strength value of 20,46 MPa and for normal concrete has a compressive strength of 20,16 MPa at the age 28 days. The compressive strength value generated by the research that occurs due to the slump test value factor that is done is not the same.                       Keywords: Concrete, scallop waste powder, Glass powder waste, concrete compressive strength.

Various strength characteristics of concrete are considered as fracture parameters. The compressive strength of concrete is of paramount importance when designing concrete structures, whereas tensile strength of concrete is the basic property when estimating cracking resistance of a structure and analysing fracture processes in concrete. When testing the compressive strength of concrete, the results are dependent on the shape and dimensions of used specimens. Some findings reported in the literature suggest that size effect exists also when testing such fracture properties of concrete as tensile strength. Unfortunately this problem is much less recognized and described compared to size effect in compressive test results. In this paper, the experimental investigation is presented on how the length of cylindrical specimens influences the tensile splitting strength of concrete obtained by means of the Brazilian method. Additional variable parameters were: type of aggregate (natural gravel and crushed granite) and cement-water ratio (C/W = 1.8 and C/W = 2.6).  In conducted laboratory experiments a higher splitting tensile strength of concrete was noted for all specimens with nominal dimensions of 150×150 mm, compared to specimens 150×300 mm in size, regardless of type of aggregate or cement-water ratio.
