CFRP Laminates for Shear Strengthening of RC Beams
The use of Carbon fiber reinforced polymer (CFRP) strips for shear strengthening of reinforced concrete beam has gain great success. Structural beams may loss shear capacity due to environmental in
Cement Types and Characteristics of Cements
Types of Portland Cement Different types of Portland cement are manufactured to meet specific purposes, as outlined by the American Society for Testing and Materials (ASTM) Designation C150, which
Setting Time of Cement Concrete – Stages and Processes
The action of changing mixed cement from a fluid state to a solid state is called setting of cement and time required for it to set is called setting time of cement. Setting time of cement is same
Understanding Chimney Damage from High-Efficiency Boiler Venting
When high-efficiency boilers are vented into traditional masonry chimneys, homeowners often notice white powdery deposits appearing on the brickwork, cracks forming around the vent connection, and a gradual deterioration of the chimney structure. These are all signs of a serious problem caused by acidic condensation reacting with the chimney flue and masonry materials. Understanding why
