Abstract

This study aims to determine the magnitude of the compressive strength of concrete by using a fine aggregate from various quarry by using SK SNI and weight ratio mixture of 1:2:3.The results showed that the maximum value of Compressive strength of concrete mixture from various quarry aggregate by using the standard SK SNI obtained at the quarry lake Bingkuang concrete at the age of 28 days at 20.94 MPa. Strong hit a maximum value of mixing concrete from various quarry aggregate by a mixture of 1:2:3 ratio was also obtained on the quarry lake Bingkuang at 28 days amounting to 21.04 MPa.From a variety of fine aggregate quarry lakes tested were Bingkuang with 1:2:3 mixture has better quality than the other quarry, the difference in two ways is not too significant because the difference in compressive strength value of 0.5% only. The best Quarry of fine aggregate is from Bingkuang Lake area, but in general all good quarry used to mix concrete, because they meet the standards of SK SNI.

Abstract

Among the factors that influence the behavior of the compressive strength of concrete after placing of concrete is the presence/absence of concrete curing and how it's cure done. Concrete curing intended as an effort to maintain the continuity of the hydration process of cement with water to binder aggregate until a certain time. Loss of water during the hydration process can reduce the quality of concrete, especially concrete compressive strength. Meanwhile in the field (on projects that are less supervision) are often encountered - especially in the column - after the mold is opened (with the opening of varying ages), concrete is left alone without curing. This research review the extent to which variations in the treatment of curing post placing of concrete affect the compressive strength of concrete. For it was made in the form of cylindrical concrete specimens with varying age of treatment (by way of concrete with a plastic cover) after the mold is opened, which is 1 day, 3 day, 7 days, 14 days, 21 days, and 28 days. In addition to the specimens was made with the standard curing for comparison.
