Results indicate that concrete containing larger size aggregates has lower spalling strength under the same loading condition. This can be attributed to the weakened strength in the larger aggregate interfacial transition zone. Results also reveal that spalling strength of concrete has a rate effect, ...
It is now commonly understood that in the design of civil engineering structures, size effect must be taken into consideration. For concrete, this problem is complex because it does not exhibit plastic softening. The failure of concrete is generally preceded by propagation of cracks, characterized ...
The strengths of porous concrete are found to be dependent on aggregate size. The rate of strength reduction of porous concrete with small aggregate size is found to be higher than that with larger aggregate size. At the same void ratio, the strength of porous concrete with large aggregate ...
Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste focuses on the recent development which the use of various types of recycled waste materials as aggregate in the production of various types of concrete.

aHowever, coarse aggregates are not used inEngineered Cementitious Concretes (hence it is a mortar rather than concrete) Silica sand is employed in the composite material in lieu of ordinary river sand (normal sand for concrete in Pakistan). 然而,没有使用粗糙的聚集体inEngineered黏结混凝土 (因此...
