問題一覧

A testing machine that may be used to conduct test site, compressive, bend, and shear test.

Universal Testing

Test that determines the stress level of a metal can withstand without failure when subjected to an infinitely number of repeated alternating stresses.

Fatigue

Test that determines the resistance of a metal to penetration.

Hardness

The minimum stress required to create permanent deformation in a metal.

Yield strength

A testing machine that may be used to conduct hardness test on metals.

Brinell Testing Machine

The process of treatment of concrete against evaporation of moisture and temperature condition.

Curing

Important property of concrete to be able to withstand deterioration due to weathering action.

Durability

The ease in which a uniform mass of freshly mixed concrete can be moved without segregation into final position in which the concrete is allowed to harden.

Workability

A test manifests the resistance of cement against deformation caused by temperature change.

Soundness

Comprises tests performed by a company receiving new supplies that the shipment meets the standards called for in the order.

Quality Assurance

Involves test done by a company on their own product that the product meets the manufacturer’s standard.

Quality Control

Required gage length (GL) of the specimen in the Tension Test of rebars.

200 mm

Structural units cast in molds in a factory that have reinforcing members not under tension as they are being cast.

Non – prestressed

Tension is applied to steel reinforcing after the concrete has been poured and allowed to harden.

Post-tensioned

Structural units cast in molds in a factory that have stresses introduced as they are being cast or after casting.

Prestressed

The process used to lower the subsurface water on a site so that the excavation remains dry and stable.

Dewatering

Construction equipment primarily used for lifting, lowering and transporting loads. They move loads horizontally by swinging or traveling

Crane

Process of bringing earthwork to the desired shape and elevation.

Grading

The lifetime of an equipment over which it can profitably survive in the face of improved models, changes in methods and techniques etc.

Productive life

Type of foundation that transmits load to the soil throughout the footing.

Spread

These are relatively long, slender members that transmit foundation loads thru soils strata of low bearing capacity to deeper soil or rock strata having a high bearing capacity.

Pile

Cement which does not only harden by reacting with water but also form a water – resistant product.

Hydraulic

Raw materials used to produce cement.

Limestone

The measure of the relative fineness of sand.

Fineness modulus

This test determines the silt and clay composition in aggregates. It also indicates the cleanliness of the aggregates.

Wash Test

This test evaluates the structural strength of aggregates.

Abrasion Test

Moisture condition of an aggregate where the surface is dry but the voids and interior of the aggregate are fully saturated.

SSD

The most important material in concrete which is held together by cement paste.

Aggregate

A standard test done on reinforcing steel bars to check its amenability to bending in structural applications.

Cold bending

A mechanical test used to evaluate the tensile properties of steel

Tension
