The invention is concerned with a concrete barrier block molded of one piece for structures that protect coast structures and river banks which have an external surface (6) the total form of which defines a smooth polyhedron (3); in accordance wit the invention, at least part of the exterior...
called the “Island of Freedom,” from the Soviet oppressed East Berlin for 28 years. Many unarmed men and women, merely seeking to be free in their own country, were shot trying to cross over the massive concrete barbed barrier. The tearing down of this bloodied Wall signaled the ...
Provided moist curing is maintained, ultimate strengths may be higher than those of ‘pure’ Portland cement concrete. The C–S–H formed has a lower Ca:Si ratio than that found in pure Portland cement (~ 1.2 cf 1.7). The nature of additions and the factors determining their performance ...
Nano-concrete refers to the usage ofnanomaterialsin concrete production, in which the size of nanomaterials is less than 500nm (Malhotra & Mehta, 2014; Aitcin, 2000). The nano-sized materials can improve engineering properties and durability of concrete products. In other words, the nanomaterials...
