Compressive Strength Of Concrete

The compressive strength of concrete is the most basic and considerable material property while reinforced concrete structures are designed. It has become a problem to use this value, however, because the control specimen sizes and shapes from country to country may be dissimilar. The study presents the results of an experiment that examined the effect of specimen size on the different classes of compressive strengths of concrete. The study included casting specimens, cubes, and six different classes of the concrete mixture. Compression tests were conducted at the age of 3, 7, and 28 days on 150 mm & 100 mm cube samples. The fresh properties of concrete were measured by slump and unit weights tests. Moreover, the specimen size of concrete has an important role both on the compressive strength and capacity of a curing cabinet. Correlations between compressive strengths and sizes of specimens are compatible for classes of structural concretes. Therefore, it can be used in curing cabinet varying sizes of concretes like 150 mm & 100 mm cube samples. Although almost 220 concrete specimens sized of 150 mm cube can be poured in curing tank, roughly 585 concrete specimens can be poured with using 100 mm cube concrete specimens. The most convenient size resulted from this study is suggested as 100 mm sized cubic specimen that it promote to change the law for concrete both curing and compressive strength test.

The main goal of this study is to find out the effect of effect of specimen shape and size, aggregate size and directions of loading and placement on the compressive strength of M20, M40, M60 and M80 grades of concrete. During the experimental study, different shaped and sized concrete specimens of different concrete mix designs were tested for compressive strength at 28 days. For casting the concrete samples, totally four different moulds were utilized, which were two different sizes of cubes and two different sizes of cylinders. The cubic moulds were 100 and 150 mm. The cylindrical moulds were 150×300 and 100×200 mm. So the relationship between size and shape effect on compressive strength of concrete samples is evaluated. Casted cubes and cylinders are tested for the compressive strength under axial compression on completion of 28 days as per IS: 516-1999.In this study, the effect of specimen sizes, specimen shapes, and placement directions on concrete compressive strengths for various grades widely used is evaluated. In addition, correlations between compressive strengths with size, shape, and placement direction of the specimen are investigated. It was found that with the increase of the size of the concrete specimen, compressive strength tends to decrease. The effect of grade of concrete on the shape effectof the compressive strength decreases as the specimen size increases regardless of strength level. Conversion factors of 0.80 to 0.90 were suggested for converting compressive strength of cylinders to compressive strength of cubes. For cubes, when the placement direction is parallel to the loading direction, the compressive strength is higher than the normal case. As aggregate size increases, compressive strength is found to be increasing.

AbstractQuasistatic compressive strength of alumina cylinders was measured using specimen of two sizes. The strength of the material was dependent on the specimen size. High speed video photography showed that the failure of the cylindrical specimen started from axial splitting, and after failure the specimen fragmentized into small pieces. A fragmentation model was proposed for estimating the average sizes of the fragments. The calculated fragment sizes agreed reasonably well with the experimental data. By using Ls-Dyna software, the failure of cylindrical specimen containing pre-existing crack-like flaws had been simulated.

Shape And Size

The purpose of this study is to investigate the influence of specimen size and shape on compressive strength of concrete. Concrete cubes, cylinders and prisms with their size ranging from 150mm to 450mm were tested in unaxial compression. Failure patterns and the effect of specimen shape and size on compressive strength of concrete were investigated. In addition, theoretical size effect models, such as the MSEL and MFSL were used to analyze the size effect of concrete strength. It is shown that for specimens tested in this study, the two models are both applicable to predicting the compressive strength of specimens in various sizes with a reasonably good accuracy.

Concrete is a technology that continues to develop in the construction sector. Continues to increase in terms of cost. The need for materials to form concrete requires innovation in the use of concrete mixtures. One of them is using the innovation of rice husk ash and ceramic waste. These ingredients is held in the cement content, namely rice husk ash containing silica and ceramic waste containing alumina. The method used refers to the Indonesian National Standard with a cylindrical specimen measuring 15x30 cm tested at 28 days, and the planned quality is fc '14.5 Mpa. The research objective was to determine the compressive strength and slump value by adding a mixture of rice husk ash 3%, 6%, 9%, 12%, and ceramic waste 3% by weight of cement. The results showed that the slump value decreased with the lowest value of 13.5 cm. the results of the compressive strength of concrete with the addition of rice husk ash and ceramic waste have not achieved the planned quality. The average compressive strength that has the highest value is the addition of 9% rice husk ash with 9% ceramic waste, namely 6.53 Mpa.Beton merupakan salah satu teknologi yang terus berkembang di bidang konstruksi.

Abstract This paper deals with the determination of compressive strength of concrete. Cubes, cylinders and re-used test beams were tested. The concrete beams were first subjected to three-point or fourpoint bending tests and then used for determination of the compressive strength of concrete. Some concrete beams were reinforced, while others had no reinforcement. Accuracy of the experiments and calculations was verified in a non-linear analysis.
