Mivan formwork is a construction technique that uses aluminum formwork system for casting concrete structures.

• Mivan formwork involves setting up aluminum formwork panels, fixing reinforcement bars, pouring concrete, and removing the formwork after the concrete has set.

• It is a fast and efficient construction method commonly used for high-rise buildings and large residential projects.

• The system allows for smooth finishes...read more

Soundness test of cement checks the ability of cement to retain its volume after setting.

• Soundness test determines the presence of uncombined lime in cement.

• It is done by mixing cement with water and gauging it with a standard consistency.

• The mixture is then made into a pat and kept in water for 24 hours.

• After 24 hours, the pat is removed and observed for any cracks or distortion.

• If the pat remains sound, the cement is...read more

Zones in beam & column refer to different regions with varying behavior and load distribution.

• Zones in a beam include compression zone, tension zone, and neutral axis.

• Compression zone experiences compressive stresses, while tension zone experiences tensile stresses.

• Neutral axis is the region where there are no stresses.

• In a column, zones include the core and the flange.

• The core carries most of the axial load, while the...read more

Mivan formwork sequence involves setting up the wall panels, fixing the corner pieces, placing the slab panels, and then removing the wall panels.

• Start by setting up the wall panels in the desired configuration

• Fix the corner pieces to ensure proper alignment and stability

• Place the slab panels on top of the wall panels

• Remove the wall panels once the concrete has set

• Repeat the process for the next level

Mix design is the process of determining the proportions of cement, water, aggregates, and admixtures to produce concrete of desired strength and durability.

• Grade of concrete refers to the strength of the concrete mix, which is determined by its compressive strength after 28 days of curing.

• Lab testing for concrete includes tests for compressive strength, slump, air content, and density.

• Mix design involves selecting the...read more

The question is related to the process of making level sheets using WMM, WBM, DBM, and BC.

• Level sheet making involves the use of different materials such as WMM, WBM, DBM, and BC.

• WMM stands for Wet Mix Macadam and is used as a base layer for roads.

• WBM stands for Water Bound Macadam and is used as a base layer for flexible pavements.

• DBM stands for Dense Bituminous Macadam and is used as a binder course layer for roads.

• B...read more

Plaster measurement involves assessing area, thickness, and volume for accurate billing in construction projects.

• Measurement is typically done in square meters (m²) for area.

• Thickness of plaster is measured in millimeters (mm) or centimeters (cm).

• Volume can be calculated by multiplying area by thickness.

• For example, a wall of 100 m² with 12 mm thickness requires 1.2 m³ of plaster.

• Consider wastage and application method...read more
