Technical field
The invention belongs to technical field of concrete, especially a kind of weight concrete.
Background technology
Weight concrete is also high-density concrete, and the major way producing weight concrete the most both at home and abroad is to use density
Relatively big (6.0g/cm3Left and right) material such as iron ore partly or entirely substitute gathering materials in general goods concrete, improve mixed
The density of solidifying soil, general density is more than 2.8g/cm3.Engineering machinery, hoisting machinery, boats and ships, traffic, water conservancy are widely used in it
Water power etc. need the engineering position of ballast, counterweight, and household electrical appliances, Body-building sandbag etc..But in the economy of current resource scarcity type
In structure, energy day is becoming tight, rapid rise of price, can be greatly increased counterweight using expensive smart iron ore etc. as concrete aggregate and mix
The production cost of solidifying soil, reduces the economic benefit of enterprise.In addition non-renewable iron ore is incorporated in concrete inherently
It it is a kind of wasting of resources greatly.
Concrete requires that 28d intensity reaches C20, and unit weight reaches 3500Kg/m3, continuous placing, mobile performance is preferable, other
No requirement (NR).
According to technology requirement, the mineral product that my company has selected three manufacturers to produce compares test.Select steel respectively
Slag, iron ore, iron ore, iron ore carry out three trials.Through trial:
(1) steel slag concrete cost is minimum, but unit weight does not reaches requirement, only reaches 3000 Kg/ m3；
(2) iron ore concrete is owing to iron ore price height is more than 4000 yuan/ton, and Cost of Concrete is too high, about needs 7000 yuan/m3, examination
It is not highly desirable for joining effect；
(3) concrete optimum of iron ore and iron ore is used to disclosure satisfy that requirement, unit weight can reach 3800 ~ 3900 Kg/
m3, cost situation is moderate.
Summary of the invention
It is an object of the invention to: a kind of unit weight height, the weight concrete of low cost are provided.
