Rigid barriers are used along roads to minimize the severity of accidents after impact. In the US, motorcycles comprise only 3% of the vehicle fleet but account for nearly half of all fatalities resulting from guardrail collisions and 22% of the fatalities from concrete barrier collisions. Hence,...
Graeme Moir, in Advanced Concrete Technology, 2003 1.6.2 Main cement types Generic types Table 1.6 summarizes the main genetic types of Portland cement produced around the world. The descriptions given in the table are very general. National (and regional) standards have specific limits for the ...

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...
