The survey showed that incompatibility between cement and admixture really exists in construction projects in Metro Manila. Incompatibility problem also exists based on the experiments of the group. This was investigated through the experimental results basing on the physical properties, such as the time of setting and the compressive strength of the concrete, and the chemical properties. Cement with large proportions of tricalcium silicate combined with a lignosulphonate-based superplasticizer may cause incompatibility problems such as early stiffening, low water reduction, and minimal increase in strength.
