“…The main objective of this research is to study the performance of cement slag in concrete through the observation of compressive strength, stress strain behaviour and modulus of elasticity with the substitution of cement slag in various percentages to observe which mixtures are most effective from various types of cement and substitution of slag and fly ash additions in the manufacture of high quality of concrete. The amount of substitution was 0%, 10%, 20%, 30%, 40%, and 50% by weight of cement, where concrete with unsubstituted cement (or 0% slag cement) was used as the control specimen [3].…”

One of the problems faced in the manufacture of high-strength concrete is the difficult workability, and the rising price of OPC and PCC cement. To overcome these problems, a self-compacting system is needed in concrete to make the workability easier to work with and the use of other types of cement besides OPC and PCC, such as the latest product HC, to reduce the cost of making high-strength concrete. The objective of this study was to compare the use of OPC, PCC and HC cement types in high strength concrete with self-compacting system, so as to overcome the high-quality problem more effectively. The manufacture and testing of test specimens were carried out at the PT Pionir Beton Industri Laboratory with the results of testing the compressive strength of OPC type cement at 955.93 kg/cm2, the compressive strength of PCC cement concrete at 866.22 kg/cm2, and the compressive strength of HC cement concrete at 885.83 kg/cm2. It can be concluded that the use of OPC cement in concrete mixes will produce the strongest concrete among the other two types of cement.

The development of construction has resulted in a higher demand for construction materials, especially concrete bricks. However, cement as one of the main components in concrete bricks has several problems. The process of cement making requires SiO2 and CaCO3 from natural sources, which can cause environmental damage. More environmentally friendly materials are needed to substitute the use of cement especially in concrete bricks. One of the materials rich in SiO2 is sugarcane Fiber ash, and materials rich in CaCO3 include eggshell powder. So, both materials are possible to be used as cement substitution materials. Innovation in form is also needed to reduce the use of cement in implementation as well as to speed up implementation time. The purpose of this research is to produce eco-friendly concrete bricks with a new design (Tetris-T model). The method used in this study is an experimental method based on SNI 03-0349-1989. The comparison of the brick mixture used is 1 pc: 6 sands with 4 variations of comparison between sugarcane Fiber ash: eggshell powder, namely variation A (0%:0%), variation B (5%: 10%), variation C (7.5%:7.5%), and variation D (10%:5%). The results of the study show that test specimen C has a compressive strength of 117.227 kg/cm2 and a water absorption of 4.87%. Based on the test results, it can be seen that variation C meets the standard requirements for SNI 03-0349-1989 quality III. The test of the effectiveness of installation on a wall measuring 1 × 1 meter shows that Tetris T innovation bricks take 38.85% less time to install compared to conventional bricks. Based on this research, reducing cement used about 15% can help the implementation of green projects to support sustainable development.
