No plastic shrinkage cracks were observed on the surface of mortar slabs reinforced with 1.5% (by volume) of 50 mm long, RP fibers.
Masonry lintels, depending on the cohesiveness of mortar, are especially weak; therefore, in masonry construction, lintels of monolithic (single slab) stone, wood, and stronger materials are used.
Masonry lintels are inefficient because they must depend on the cohesiveness of mortar, which is weaker than the blocks it bonds; so, in masonry construction, lintels of monolithic (single-slab) stone, wood, and stronger materials are employed.
1. Watch me, I'm running, watch me, I'm dancing, I'm air; the building I used to live in has been razed and I'm skipping, hopping, two-footedly leaping across the blocks, bricks, slabs of concrete, plaster, and other unnameable junk... Or nameable, really, if you look at the wreckage closely... Here, for instance, this shattered I-beam is the Bible, and this chunk of mortar?
