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 ...
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
mind the cost efficiency, availability of materials, quick time of fabrication and flexibility of extension and portability.

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.
Methods of Strengthening Concrete Columns
Column strengthening is a process used to add or restore ultimate load capacity of reinforced concrete columns. It is used for seismic retrofitting, supporting additional live load or dead load that not included in the original design, to relieve stresses ...
Bubble Deck Slab – Types, Material Specification, Installation, and Advantages
Bubble deck slab is a hollow, flat slab that spans in two directions, in which plastic balls are incorporated to replace, and therefore eliminate the concrete in the middle of a conventional slab which does not contribute to its structural ...
