Abstract
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.

Summary
Perkembangan teknologi semen menjadi pemicu pertumbuhan industri semen di dunia dengan bermunculan pabrik semen. Beberapa hasil penelitian sejenis terdahulu yaitu penggunaan semen PCC merupakan salah satu alternatif solusi untuk menghasilkan beton yang berkualitas baik, namun dengan harga yang lebih ekonomis dan lebih ramah lingkungan [1]. Penambahan silica fume pada semen tipe PCC menunjukkan nilai kuat tekan, kuat tarik belah dan porositas yang lebih baik. Kenaikan kuat tekan mempunyai korelasi dengan kenaikan kuat tarik belah dan penurunan porositas [2].
