| dc.description.abstract | The increasing demand for cement due to the development of construction
using concrete materials is causing cement prices to rise over time.
Currently, there is much research on materials that might replace cement.
In terms of quality, the compressive strength of concrete is influenced by
several factors, namely the materials used and the concrete curing
methods. Therefore, this research was conducted to determine the effect
of mixing lime powder as a cement substitute and also the effect of
concrete curing. The method used for the mix design is based on SNI 03-
2834-2000 and the method used for compressive strength testing is based
on (Badan Standarisasi Nasional, 2011). The proportions used in this
substitution involve lime powder at percentages of 5%, 10%, and 15%.
Two curing methods were used: the soaking method and the burlap sack
covering method. Generally, the research results show that the soaking
method provides higher compressive strength test results in all variations
compared to the burlap sack covering method. The optimal compressive
strength value in the soaking method was obtained at the 10% variation
with 31.77 MPa, and for the burlap sack covering method, it was obtained
at the 15% variation with 25.80 MPa. | en_US |
