Protection systems of joints include the sealing of cracks, contraction (control) joints, expansion joints, and construction joints. Joint sealants in concrete minimize the intrusion of liquids, solids, or gases, and protect the concrete against damage.

Mix Design of High-Strength Concrete: Methods, Procedure and Example
Mix design of high strength concrete is influenced by properties of cement, sand aggregates & water-cement ratio have compressive strength above 40 MPa. To achieve high strength, it is necessary to use lowest possible water-cement ratio, which invariably affects the ...
Applications of Fiber Reinforced Concrete in Pavements
There are various applications of fiber reinforced concrete and one of them is in the construction of concrete pavements. Fiber reinforced concrete (FRC) is defined as a composite material consisting of concrete reinforced with discrete randomly but uniformly dispersed short ...
What is Distress of Concrete and its Remedial Measures?
What is Distress of Concrete? Distress in concrete members occurs with age due to corrosion in reinforcement, loading, settlement of foundations etc. This distress in in building can be found by development of cracks in concrete members such as slabs, ...
LOW COST FERROCEMENT EARTHQUAKE RESISTANT HOUSE
Ferrocement is a type of thin wall reinforced concrete commonly constructed of hydraulic cement mortar reinforced with closely spaced layers of continuous and relatively small size wire mesh. The mesh may be made of metallic or other suitable materials.
Ferrocement has a very high tensile strength-to- weight ratio and superior cracking behavior in comparison to conventional reinforced concrete. This means that thin ferrocement structures can be made relatively light and watertight. Hence, ferrocement is an attractive material for the construction of prefabricated housing units, boats, barges, and other portable structures.Ferrocement, a material recommended by ACI 549R-97, is proposed for this house. Ferrocement performs excellently due to its closely distributed reinforcement. This will be a very economical option for temporary and permanent construction for the years to come. Shortly after the earthquake this design was proposed, keeping in

No level of earthquake preparedness can guarantee that an earthquake will not damage a building. Structures cannot be completely earthquake-proof, but good seismic design will minimize structural damage, and the most importantly, safeguard the lives of the occupants during a major seismic event. Seismic resistance is best achieved by following modern building codes and standards and in large or complex.
