WebABSTRACT. Tests have been performed to determine the fire resistance of load-bearing and non-loadbearing walls of concrete blocks, both solid and hollow, made with two types of aggregate. The information from the tests has made it possible to make a more complete assessment of the fire resistance of concrete block walls, but some further work ... Webfrom the sun or from a fire. The greater the wall’s mass, the higher its heat storage capacity, and the higher its fire resistance rating. Solid units (those with less than 25% cored area) have the highest mass and therefore the longest fire resistance rating (see Table 1). Since hollow units (those with more than 25% c o r e d a r e a )
