grinding a concrete beam

Concrete grinding a capping beamApr 3, 2013 . Concrete grinding a capping beam which has blown out.grinding a concrete beam,Effects of used Engine Oil in Reinforced Concrete Beams - wasetolder cement grinding unit resulted in concrete with greater resistance to freezing and thawing. This effect was thought to be similar to adding an air-entraining chemical admixture to concrete. This paper presents an investigation on the load deflection behaviour and crack patterns of reinforced concrete (RC) beams.
