Types of concrete test that is done to assess the plasticity and workability of concrete of each concrete mix. It uses slump cones that have a height of 300mm, with the bottom part having a diameter of 200mm while the upper part has a diameter of 100mm.

A

Slump test

143
Q

Types of concrete test that is done through subjecting a cylindrical sample of a cured concrete mix into a hydraulic press to determine its maximum load capacity before the concrete fails or fractures.

A

Compression test

Q

“Off-site concrete mixing is usually done in centralized ready-mix plants.” True or false?

A

True

145
Q

It is the phenomenon where the coarse aggregates settle at the bottom part of the formwork while the cement and sand mixture are above.

A

Concrete segregation

146
Q

It is the method of removal of voids on a freshly poured concrete. This is done to ensure that the concrete evenly covers the formworks.

A

Consolidation

147
Q

Q

It is one of the recent innovations in building construction. Another name for this is Autoclaved aerated concrete. Made out of cement and aggregates + expanding agent(comprises 80% of material composition). It has insulation and structural capabilities that are often used as walls, ceilings and roofs.

A

Aerocrete

152
Q

It is a type of concrete known for its method of application similar to being shot from a gun.

A

Gunite (shotcrete)

153
Q

It is known as expanded shale concrete. Instead of gravel as coarse aggregate, it uses clay, shells and slates that were expanded through high temperatures. Lightweight concrete that is strong, fire resistant, and has good acoustical properties.

A

Haydite concrete
