Description
Technical field
The present invention relates to radiation shield concrete material field, more particularly, relating to a kind of is steel slag radiation shield concrete and preparation method thereof aggregate, that have shielding X ray, gamma-rays and neutron radiation effect with the slag.
Background technology
Radiation shield concrete is called shielding concrete, loaded concrete again, and it can effectively shield nuclear radiation.So-called nuclear radiation generally is meant alpha-ray, β ray, gamma-rays and neutron current.Because alpha-ray, β ray penetration power are lower, the protective material that thickness is very little also can block them fully, so the ray that radiation shield concrete will shield mainly is gamma-rays and neutron ray.The aggregate of common radiation shield concrete generally adopts mineral materials such as barite, magnetite, limonite, still, adopts these mineral materials to do to gather materials, easily emanate, the concrete construction poor performance, hydration heat of cement is big, concrete is easy to crack, poor durability, and the curing safe effect of nuke rubbish is poor; In addition, these mineral materials are natural resources in short supply, and excessive exploitation is unfavorable for Sustainable utilization of resources.On the other hand, along with the raising year by year of China's iron and steel output, the output of slag also increases thereupon, and a large amount of slags all need the big area soil to stack every year, all brings serious pollution for soil, water body, atmosphere etc., even people's health is constituted a threat to.In the international environment that is becoming tight energy day now, how to develop the high added value comprehensive Utilization Ways of solid waste, become the key that realizes iron and steel enterprise's cycle development.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of steel slag radiation shield concrete and preparation method thereof is provided.
Know-why of the present invention is to utilize slag hardness height, manys micropore (the cement that passes through that can be more firm bonds than great, surperficial, increase compactness) characteristics, it is prepared the very fine and close superheavy concrete of structure as aggregate, to reach radiation-resistant effect.
Concrete technical scheme of the present invention is as follows:
A kind of steel slag radiation shield concrete, the parts by weight of its component are as follows: cement 1, water 0.4-0.5, slag sand 4-8, water reducer 0.01-0.03, barite 0.01-2, colemanite 0.01-0.03; Described slag sand by 0-5mm and two kinds of particle size range of 5-25mm in 1～3: 1～3 ratio is formed, and is preferably 1: 1, and f.CaO content≤3% of slag sand; Described water reducer is selected from FDN water reducer and polycarboxylate dehydragent; Described steel slag radiation shield concrete apparent density＞2900kg/m
