As a result of a number of reasons new interest developed into the use of lightweight aggregate concrete. Within the scope of this development, a modernized code for lightweight concrete had to be written. In order to support this development, a number of research projects have been carried out. The aim of the research was to verify the appropriate...

... Equations (1) and (2) give shear stress and normal stresses due to aggregate interlock as a function of the crack kinematics (sliding and crack width) and concrete strength. The aggregate effectivity factor, C f , was originally introduced by Walraven and Stroband [25], representing the aggregate fracturing. The C f can vary between 1 and 0.35 where 1 represents no aggregate fracturing, while 0.35 represents complete aggregate fracturing. ...
... The sintered fly ash aggregate concretes can produce superior compressive strengths but consumes more energy in the aggregate production process. The effect of replacing quarried aggregate by fly ash aggregate in concrete provides mixed results, whereas a few studies reported higher mechanical performance than quarried aggregate concrete [17][18][19], others reported lower compressive strengths [20][21][22][23]. It was noted that fly ash aggregate concrete displayed lower elastic modulus than quarried aggregate concrete, ranging between 12.65 and 30.2 ...
