Keruntuhan geser pada balok beton bertulang tanpa tulangan geser merupakan keruntuhan yang sangat getas. Sejumlah besar penelitian eksperimental mengenai keruntuhan geser balok beton bertulang menunjukkan fakta bahwa kegagalan geser balok merupakan proses yang kompleks dan adalah efek dari berbagai parameter yang memberikan pengaruh signifikan, diantaranya kuat tekan beton (fâ€²c), rasio bentang geser-tinggi efektif (a/d), rasio tulangan longitudinal (), dan tinggi efektif penampang (d). Oleh karena itu, upaya untuk memperoleh model prediksi yang mampu memberikan hasil yang paling mendekati mekanisme geser menjadi daya tarik kuat bagi para peneliti. Penelitian ini bertujuan untuk mengevaluasi dan membandingkan enam perumusan geser berdasarkan ACI 318, EC2, CSA A23.3, BS 8110, NZS 3101, dan CEB-FIP dengan data eksperimen kuat geser beton yang diperoleh dari literatur; mengusulkan suatu persamaan desain untuk memprediksi kekuatan geser beton (Vc) balok beton bertulang tanpa tulangan geser; serta merekomendasikan model usulan sebagai salah satu alternatif perhitungan geser bagi praktisi desain selain perumusan geser berdasarkan standar. Persamaan yang diusulkan berasal dari hasil analisis regresi dengan menggunakan 276 data hasil uji geser balok yang dikumpulkan dari 20 sumber dengan berbagai variabel yang mempengaruhi kekuatan geser. Kekuatan geser beton hasil eksperimen sebelumnya dibandingkan dengan model usulan dan ke-enam perumusan geser beton tersebut diatas. Hasil evaluasi ke-enam standar menunjukkan bahwa standar beton menurut CEB-FIP dan BS 8110 menunjukkan hasil prediksi yang lebih baik dan konservatif terhadap hasil tes daripada standar ACI 318-14, NZS 3101, CSA A23.3, dan EC2. Perumusan geser berdasarkan ACI 318-14, CEB-FIP dan BS 8110 menghasilkan prediksi kekuatan geser beton cenderung aman dibandingkan ke-tiga standar beton lainnya (NZS 3101, CSA A23.3, dan EC2). Dari hasil analisis, diusulkan dua persamaan kekuatan geser beton balok bentang pendek dan panjang tanpa tulangan geser yang dibatasi dengan rasio kelangsingan balok, a/d â‰¥ 2,5 dan 1,5 â‰¤ a/d < 2,5. Model usulan cukup akurat (applicable) memprediksi gaya geser beton Vc balok beton bertulang bentang pendek maupun panjang tanpa tulangan geser pada rentang variabel yang dipertimbangkan dalam penelitian ini.

Generally, factory waste cannot be disposed of directly because it can pollute the environment. In the city of Makassar, South Sulawesi, to be precise at PT. Makassar Tene uses coal as factory fuel, where the rest of the coal combustion produces fly ash and bottom ash waste which requires processing before disposal. This study aims to determine the value of compressive strength, split tensile strength and flexural strength of concrete and to determine the effect of the percentage of fly ash and bottom ash substitution in the concrete mixture. This research was conducted using the American Concrete Institute (ACI) method with a design quality of 23 MPa. Based on this research, it can be seen that the concrete mixture with fly ash and bottom ash substitution causes the concrete to experience a decrease in strength as the percentage of bottom ash substitution increases.

The main constituent of cement is calcium carbonate. In concrete mixing, a materiaI that can be used as a substitute for partial cement is calcium carbonate. The purpose of this study is to determine the compressive strength, spIit tensiIe strength, and flexural strength of concrete using calcium carbonate as a substitute for partial cement in high quality concrete. The research methodology started from examining the characteristics of the aggregate, calcium carbonate, and mix design (SNI 03-2834-200), manufacturing of cylinder and beam specimens. The results show that the composition of the concrete mixture using calcium carbonate as a cement substitution indicates that the higher the percentage of variation in calcium carbonate will reduce the quality value of the concrete.

The column interaction diagram is a boundary area graph showing the various combinations of axial loads and moments that the column can safely hold. The benefit of a column interaction diagram provides an overview of the strength of the column in question. This study aims to analyze rectangular and circular columns using column interaction diagrams and then compare the strength of the columns in withstanding a combination of axial loads and bending moments with the same area. In this study, square and circular columns have the same number of reinforcement, diameter of reinforcement, steel strength, concrete quality, and cross-sectional area. The column is reviewed based on five conditions, namely pure axial load conditions, pure bending moment, and three failure conditions. Based on the five conditions that occurred, a column interaction diagram was created by using Microsoft Excel. Results of the analysis show that in the same area, the square column is stronger in withstanding the bending moment (Mu) of the circular column by 0.015 - 0.61%, while the circular column is stronger in resisting the axial force (Pu) of the square column by 1,9 - 4.4%.

Along with the increasing pace of development, many methods and research have been carried out and developed aimed at increasing the strength of concrete, one of which is by utilizing waste rice snail shells as a partial replacement of cement. This snail is considered a pest for farmers. Snail carcasses can also damage the environment and cause a bad smell. This can be used and utilized as an alternative material in concrete mixtures. The percentage of use of rice snail shell substitution varied, namely 0%, 10%, and 15%. The tests carried out were the compressive strength test, split tensile strength test, flexural strength test, and the modulus of elasticity of concrete with a concrete quality of 25 MPa. The test objects used were cylinders measuring 15 cm and 30 cm high and beams measuring 60 cm × 15 cm × 15 cm with variations in age of 7 days, 21 days, and 28 days. The highest value was obtained at 10% snail shell variation with 27,540 MPa, 2,735 MPa, 4,131 MPa, respectively. so that the 10% snail shell variation used in this study is still safe to use as a cement substitution material in normal concrete mixtures.

Cement is the basic material for making concrete that can be used as a hydraulic binder. There are various types of cement including OPC and PCC cement. The problem now is that there is no technical data that can be used as a reference in determining the proportion of the mixture. Examples of cement are obtained from the same factory. namely PT. Semen Tonasa, South Sulawesi with an amount of 78.96 kg of cement for each type of cement. From the results of laboratory tests, it was found that the data on the comparison of concrete using OPC and PCC cements had different data on the of OPC cement is 3.726 Mpa and PCC cement is 3.223 Mpa and for testing the modulus of elasticity of OPC cement is 19371.316 Mpa and PCC cement is 17579.182 Mpa. The test results have met the standard for structural concrete with the same water-cement factor.

Geotextile is made of permeable geosynthetic. Geotextile s are formed from synthetic fibers based on polymers that have high mechanical properties in tensile strength, trapezoidal tearing strength, and puncture resistance. Therefore, researchers want to increase the use of Geotextile as an added material in the tensile area of concrete blocks. The test objects used are 9 pieces of 150mm×150mm×600mm beams. The results of the research were that the addition of woven Geotextile s and non-woven Geotextile s on concrete blocks increased, for woven Geotextile s by 21.593% of beams without using Geotextile s and non-woven Geotextile s of 17.058% of beams without using Geotextile s. So the use of Geotextile s on concrete blocks can improve quality because the value of the flexural strength of beams using Geotextile s is greater than beams without using Geotextiles.

Because of the transformation of the load of an arrangement on the building infrastructure can receive the load outside the original plan, for that it is necessary to strengthen the structure so that the structure of the building remains safe. In this study the use of woven &non-woven fibers in new concrete is expected to increase strong press, strong tensile and modulus elasticity to conventional concrete. The mix design of the study uses the American Concrete Institute (ACI) method. The test sample of 36 was then divided into 3 variations. The results of this study have shown the addition of strong press, strong pull, and modulus elasticity. Strong press for woven increased 29.485% % and non-woven increased 7.296%, strong pull for woven increased 24.633% and non-woven increased 5.285%., modulus elasticity for woven increased 20,924% and non-woven increased 9.356%. For the comparison of both materials, woven is stronger than non-woven.
