THE FUNDAMENTAL STUDIES ON THE FLEXURAL AND SHEARING PROPERTIES OF CONCRETE BEAMS WITH ARTIFICIAL LIGHTWEIGHT AGGREGATE

Abstract

( 1 ) Test specimens Fourteen beams were fabricated. All beams are of 10 •~ 20 cm section and 150 cm long as shown in Fig. 1. Round bar of dia. 6 mm is used as stirrups. As the longitudinal reinforcement two round bars or deformed bars are used in the tension side and two round bars of dia. 9 mm in the compression side, also as shown in Fig. 1 and in Table 1. Beams of series L and N are made of lightweight concrete and normal weight concrete, respectively. ( a )
