1.05 DEFINITIONS
A.blast-furnace slag: The non-metallic product, consisting esntially of silicates and
alumino-silicates of calcium and of other bas that is developed in a molten
condition simultaneously with iron in a blast furnace.
B.blended cement: A hydraulic cement consisting esntially of an intimate and
uniform blend of granulated blast-furnace slag and hydrated lime; or an intimate and
uniform blend of portland cement and granulated blast-furnace slag, portland cement
and pozzolan, or portland blast-furnace slag cement and pozzolan, produced by
intergrinding portland cement clinker with the other materials or by blending portland
cement with the other materials, or a combination of intergrinding and blending.
C.bulk cement: Cement that is transported and delivered in bulk (usually in specially
constructed vehicles) instead of in bags.
D.fly ash: The finely divided residue that results from the combustion of ground or
triedpowdered coal and that is transported by flue gas from the combustion zone to the
particle removal system.
E.mineral admixtures: A material other than water, aggregates, hydraulic cement,
and fiber reinforcement, ud as an ingredient of a cementitious mixture to modify its
考试心理freshly mixed, tting, or hardening properties and that is added to the batch before
or during its mixing.
F.pre-packaged cement: Cement is packed in tight bag and the net weight shall be
50 kg with a tolerance of ± 2% and with marking of type of cement, name of the
manufacturer or trade mark, net weight in metric units and the number of standard.
G.portland cement: A hydraulic cementing material for mortar and concrete, resulting
from grinding and pulverising the burned calcareous or lime bearing materials with
argillaceous or other silica, alumina and iron oxide bearing materials (clinker), with
the addition of gypsum or its derivative or water or both.
H.silica fume: A very fine non-crystalline silica produced in electric arc furnaces as a
by-product of the production of elemental silicon or alloys containing silicon. It is also
