Abstract
Plastiment P-121R is a solid polymer based product and has the effect of slowing down the concrete binding time. The data used in this study consisted of two types of data, namely primary data and secondary data. Primary data is data that is collected and processed directly from the subject or object of research, in the form of testing data for concrete constituent aggregates and concrete compressive strength at each variation of mixing time, namely 60 minutes, 90 minutes, and 120 minutes and variations in the provision of plastiment-added materials, namely 0.2%, and 0.4%. From the test results show that the influenceThe length of time mixing the compressive strength of the concrete with the added material of Plastiment P-121R in the provision of added material variations of 0.20%, the value of the compressive strength of concrete is 17.55 to 18.85 MPa while the added material variation of 0.40% is 17.27 up to 22.08 Mpa.
