Cement grouting is done to seal a wide crack especially in gravity dams, canal linings, foundation, and thick concrete wall. This is general grouting in construction. It is composed of neat cement and water or mixture of a sand (4 parts) to cement (1 parts). Before injecting, holes are bored around the field to be excavated with a thin grout.

Grade of concrete ( M-10) → 1: 3: 6 (cement: sand: aggregates) M-10 grade concrete will give a total characteristic strength of 10 MPa. Lean concrete is a mixture where the amount of cement used is less than the amount of liquid present in the strata.Lean concrete is that concrete which has high aggregates to cement ratio.

Located in More Hall, the Construction Materials Laboratory is an instruction lab for both CEE students and students in the Construction Management Department in the College of Built Environments. Students in both departments learn about materials such as steel, aluminum, wood, aggregates, portland cement concrete and hot mix asphalt. The lab allows students to do all of the mix design

It is an ingredient of concrete. Concrete is a blend of cement, water, and stone and sand aggregates. As a construction material, it has excellent compressive strength and fire resistance. This article explains the differences between the different types of cement used in construction and civil engineering. Portland Cement

Generally, M5, M10, M15 grades of concrete are used for PCC (plane cement concrete) work like leveling course, for bed footing etc. Unit weight of plain cement concrete (PCC) is 2400 kg/m 3 or 24 24 KN/m 3. Unit weight of reinforced cement concrete (RCC) is 2500 kg/m 3 or 25 KN/m 3.

Properties of Concrete: Concrete is a composite material obtained by mixing Cement, sand, aggregates, and water in suitable proportions. Concrete has become a universal building material which is extensively used in civil engineering construction.

Disadvantages of reinforced cement concrete: The tensile strength of this concrete is 1/10 of its compressive strength. The price of this concrete used for casting is comparatively excessive. The RCC column section is larger than the metal section for multi-story construction. Due to the shrinkage, the crack increases and the strength decreases.

In the United States, in response to widespread cracking of concrete bridge decks, the construction process moved towards the use of High Performance Concrete (HPC) mixes. Four types of HPC were developed 1 : Very High Early Strength Concrete - 17.5 mPa in 6 hours. High Early Strength Concrete - 42.5 mPa in 24 hours.

Civil Engineering Materials. The modern civil engineer needs to deal with traditional construction materials as well as advanced materials. Traditional construction materials, such as timber, steel, asphalt and Portland cement concrete are often used in many construction projects. Modern materials, such as polymers and composites are making

Placing Portland Cement Concrete Pavement (PCCP) is one of the final steps involved when building a road, but it's far from an afterthought Type of pavement is a consideration very early in the planning phase when designers look into various factors, including pavement design life, traffic volume and type, soil conditions and maintainability.

Sea sand does not have high compressive strength, high tensile strength, so it cannot be used in construction activities. Sea sand contains salts which deteriorates the plastered surface and the slab surface and in the long run cause seepage in the building. The salt in sea sand tends to absorb moisture from atmosphere, bringing dampness.

Based on structural design requirements the grade of concrete construction is selected and there are two types of concrete mixes, design mix & nominal mix. The grades of concrete are converted into mix proportions consider for M20 concrete mix proportion will be 1: 1.5: 3 (cement, sand and coarse aggregates).

The strength measure with concrete cube or cylinders by civil engineers at the construction site. Cube or cylinders make during casting of the structural member and after hardening, its cure for 28 days. Then the compressive strength test conducted to find the strength. Regular grades of concrete are M15, M20, M25, etc.
