Preventing plastic shrinkage cracking by monitoring the capillary pressure build-up in self-compacting concrete [PDF]
Plastic shrinkage cracking is a problem for the service life, aesthetics and durability of concrete members. It occurs when tensile stresses are induced in fresh concrete, through plastic shrinkage that is restrained.

The influence of temperature on the cracking of plastic concrete [PDF]
High early age concrete temperatures can lead to many problems such as an increased rate of cement hydration, as well as an increased rate of moisture loss from fresh concrete which can ultimately lead to the occurrence of plastic shrinkage cracking ...

Assessment of Shrinkage Strain Reduction SSR for RC Slabs with Different Thicknesses Strengthen with Different Layers of Geogrid [PDF]
This study presents experimental work to evaluate the efficiency of using the biaxial geogrid as a shrinkage reinforcement for RC slabs instead of using upper shrinkage steel reinforcement. Geogrid distinguish from steel reinforcement in its low cost and

The Influence of the Processing Conditions on Changes in Physical and Structural Properties of Injection Moulded Parts Made of Polypropylene [PDF]
The injection moulding conditions may change the degree of crystallinity of the plastic to some extent, which affects the mechanical properties such as tensile strength and hardness. Moreover, the cooling conditions of the moulded parts may contribute to
