Compressive Strength Of Concrete

Plastic Material Plastic waste is a problem that is very often encountered in urban and rural areas. The use of plastic in each year will continue to increase because food and beverage products all use materials made of plastic. However, the plastic in question is plastic that is difficult to contaminate with soil or commonly referred to as inorganic waste, which is difficult to self-destruct. This is what causes the amount of plastic waste to increase.Therefore, to reduce this waste, the volume of this waste is used in the development. Besides, the grain gradation of the aggregate has been determined with the aim of obtaining an increase in the compressive strength of the concrete with the addition of plastic waste. The quality of the concrete to be examined by the authors in this study is fc = 14.5 MPa. In other words, in this study the author tries to compare the compressive strength of concrete between normal concrete and concrete mixed with plastic waste. In this study also used a variation of plastic waste substitution with a ratio of 0%, 5%, 10% to the volume of fine aggregate. For each variation, 2 samples were used which included normal concrete so that the total test object used was 12 tested at 7 days, 14 days and 28 days of concrete.From the results of testing the compressive strength of concrete against normal concrete and mixed concrete with sawdust surian at the age of 28 days, the normal concrete compressive strength is 14.5 MPa, while in the sawdust mixture with a percentage of 5%, the concrete compressive strength is 14.14 MPa. 10% obtained a compressive strength of 17.05 MPa. From this test, it can be concluded that from each of the percentages that are made, the compressive strength increases along with the percentage of the amount of plastic waste added to the concrete mixture. In other words, the greater the percentage of plastic waste used, the higher the compressive strength and quality of the concrete produced.

The Pumice sand is a bright colored butian type, containing foam made from glass-walled bubbles and usually referred to as silicate volcanic glass granules. This pumice sand can be used as a substitute for normal sand as fine aggregate in a mixture of concrete mix. Based on the characteristic test examination, it can be seen that in testing the characteristics of pumice sand to the specifications of normal sand in specific gravity testing and weight testing of quicksand obtained results that are smaller than the specifications of normal sand and absorption tests obtained results greater than specifications on normal sand. The results of the normal sand compressive strength at BN is 250.95 kg /cm2 while the results of the floating sand concrete compressive strength on BPA is 224, 965 kg /cm2. Based on the research it can be concluded that with the same quality of concrete, the quality of K-250 is different in comparison to the compressive strength of concrete in normal sand and pumice sand concrete shows almost the same results. Therefore, more in-depth research is needed regarding the use of pumice sand instead of normal sand in a mixture of concrete mix

Normal concrete uses fine aggregate and coarse aggregate with concrete density 2200 kg/m3-2400 kg/m3 with a compressive strength of about 15-40 MPa [1]. The purpose of this study is to determine characteristics of the concrete aggregate and the compressive strength of the concrete design based on the DOE (Department of Environment) method and the SNI Standard. In this research, the use of nugmet shell was varied as follows: 0%, 0,25%, 0,50%, 0,75% and 1% of the cement weight. The results showed that the use of nutmeg shells as a normal concrete affected the specific gravity and the value compressive strength of concrete. The higher the percentage of nutmeg shells, the lower the specific gravity and compressive strength of the concrete. The average value of density to nutmeg shell concrete (NSC) 2254.72 (kg/m3) and normal concrete 2304.32 (kg/m3). The compressive strength of normal concrete is 224.2 kg/cm2 and the nutmeg shell concrete (NSC) the composition of 0.25% and 0.5% obtained by 129.6 kg/cm2 and 140.0 kg/cm2 increases the use of nutmeg shell 0.75% and 1% obtained value ​​of 117.6 kg/cm2 and 118.1 kg/cm2 decreased at the age of 28 days. The compressive strength of normal concrete 22 MPa while the maximum nutmeg shell concrete (NSC) 14 MPa, so it does not meet the quality of normal concrete in general.

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.
