ABSTRACT: Concrete as a civil
building construction materials have a deficiency or loss that is about the
size of the dead load weight of the concrete itself. Dead load on the building
structure can be minimized by the use of lightweight concrete. To get a
lightweight concrete that meets the quality or value of concrete compressive
strength, is strongly influenced by the selection of coarse aggregate and mix
proportion of concrete used. Concrete is called lightweight concrete if volume
weight is 1400-1850 kg/m3 (ACI 213R-79). The purpose of this research is to
investigate the values of compressive strength of lightweight concrete
aggregates ALWA with the Dreux-Corrise Method. Specimens consist of 15 pieces
of concrete cylinders (d = 150 mm, t = 300 mm) for lightweight concrete ALWA
with the Dreux-Corrise Method. Treatment of samples was done by soaking and
aerated for 7 days. Compressive strength testing performed on specimens aged 28
days. There are 3 specimens for 3 days, 7 days and 14 days for compressive
strength, and there are 6 speciments for 28 days compression test. The results
showed average for compressive strength are 9,38 MPa; 7,86 MPa ; 13,30 MPa dan
20,59 MPa for 3 days; 7 days; 14 days and 28 days respectively. The average
value of the compressive strength obtained from the Dreux-Corrise Method was
20,59 MPa (28 days) lower than targeted of 24,5 MPa.
