## Abstract
Abstract The purpose of this study is to determine the initial characteristics of foam concrete mixtures. This performance, using Ordinary Portland Cement (OPC) and Portland Composite Cement (PPC) were examined for its density and compressive strength on day 1, 3 and 7. In addition, the production process was initiated by formulating a mix of foam solvent, simultaneously creating the mortar, with the use of OPC or PPC, followed by the individual integration of a foaming solvent. Furthermore, after density evaluation, a specimen is produced with the cylinder cast, in a diameter of about 150 mm, and length of 300 mm, containing individual water and atmosphere curing. The density obtained was higher than the outcome of air curing tests, which decreased continuously with the concrete age. Furthermore, the compressive strength measured was relatively lower in water curing testing, using PCC, and on day 7it w was up to 3.46 MPa, or 73.5%, which seems to be lower than the record obtained with the use of OPC, which was about 3.94 MPa. At similar age, the value obtained for air curing with PCC reached 4.52 MPa or 96.0%, exhibiting a lesser value than OPC (4.71 MPa).
