What's the difference between "regular" and "Type X" gypsum board?

ASTM C 36 designates two types of gypsum board, regular and Type X. Type X gypsum board, which is typically required to achieve fire resistance ratings, is formulated by adding noncombustible fibers to the gypsum. These fibers help maintain the integrity of the core as shrinkage occurs, providing greater resistance to heat transfer during fire exposure.To receive the "Type X" designation under ASTM C 36, a gypsum board product must be shown to achieve not less than a one-hour fire resistance rating for 5/8" board or a 3/4-hour fire resistance rating for 1/2" board applied in a single layer

non-combustible means

It will not ignite and burn when subject to fire

construction type refers to

fire resistance ratings of various building compenents

waterproofing uses these applications

watertight membranes, waterstops, or bentonite panels



typically built below the water table

dampproofing

control of water and moisture when hydrostatic pressure is not present



applications include admixtures for concrete, bituminous coatings, cementious coatings, membranes, and plastics for dampproofing



typically at grade

surcharging

the preloading of the ground with fill material to cause consolidation and settlement of the underlying soil. It is used to increase the bearing capacity of the soil

waterproofing

the control of water and moisture that is subject to hyrdostatic pressure.



applications include watertight membranes (elastomeric membrances, liquid applied membranes), waterstops, bentonite panels



typically below the water table

bentonite

a type of expansive clay that can push foundations and floor slabs upward when it gets wet. To prevent this you may use a combination of drilled piers, grade beams, and voids left below grade



bentonite panels are also used for waterproofing below grade

electrical resistances test

determines the moisture in concrete by measuring the electrical conductivity with meter probes

cylinder test

requires a sample to be taken at the time of the concrete pour before it is hardened

core cylinder test

gives the strength of the hardened concrete

Kelly ball test

requires a sample to be taken at the time of the concrete pour before it is hardened

Type I

General purpose



Fairly high C3S content for good early strength development



General construction (most buildings, bridges, pavements, precast units, etc)


Type II

Moderate sulfate resistance



Low C3A content (<8%)



Structures exposed to soil or water containing sulfate ions


Type III

High early strength



Ground more finely, may have slightly more C3S



Rapid construction, cold weather concreting

Type IV

Low heat of hydration (slow reacting)



Low content of C3S (<50%) and C3A



Massive structures such as dams. Now rare.

Type V

High sulfate resistance, gains strength slower



Very low C3A content (<5%)



Structures exposed to high levels of sulfate ions

Type M

High strength mortar



masonry below grade



subjected to hight lateral or compressive loads or severe frost action

Type S

Medium-high strength mortar



Generally above grade (exterior)



high flexural bond strength but subjected only to normal compressive loads

Type N

Medium strength mortar



Generally above grade (parapet or interior)

Type O

Medium low strength mortar
