THESIS A STUDY OF THE DURABILITY OF CONCRETE

The laitance formed in sea-water concrete is partly cement rising to the surface and partly magnesia precipitated from the sea water. Extreme care should be used to remove this film before more concrete ie laid because it forms an excellent point of attack for sea water. In

The results showed that all three types of fibers increased the shear capacity of the beam specimens more than the beam reinforced with minimum shear reinforcement. Moreover, some of the fibers used could shift the type of failure from a pure shear failure to a

Lightweight Insulating Concrete TopDissertations

Lightweight insulating concrete (LWIC) is a material used for insulation purpose as a substrate for attachment or support of roofing membranes on slope roofs. Insulation is the process of introducing a barrier to a delicate component to save it from damages. LWIC systems are derived from cellular concrete or a composition of aggregate materials.
