Description
Technical Field
The present invention relates to a hydrated cured product and a method for producing the same.
Background
Conventionally, a hydrated cured product such as concrete or mortar has been known. In general, the hydrated solidified body is obtained by solidifying a kneaded product containing: aggregates (fine aggregates and coarse aggregates) of different particle sizes such as natural crushed stones and mountain sands; a binding material such as cement which cures by a hydration reaction; and water.
As such a hydrated solidified body, a hydrated solidified body using an aggregate containing a steel-making slag (hereinafter, also referred to as "steel-making slag hydrated solidified body") is known (for example, see patent document 1), which is used for harbor civil engineering materials, road base materials, and the like.
The steel-making slag is a high-specific gravity and hard substance containing a large amount of iron component, and has various particle sizes, and thus can be used in the form of fine aggregate or coarse aggregate. In the case where the steelmaking slag hydrated solidified body is used for a harbor civil engineering material (for example, a wave-absorbing block, a fish reef block), the specific gravity of the harbor civil engineering material can be increased, and therefore the steelmaking slag hydrated solidified body can be said to be a material suitable for the harbor civil engineering material.

Detailed Description
[ hydrated cured body ]
The hydrated solidified body of the present invention is a hydrated solidified body obtained by solidifying a kneaded material containing an aggregate containing a steel-making slag, a binder solidified by hydration, and water, wherein the aggregate has a maximum dimension of 5mm or more and 60mm or less, a solid volume fraction of coarse aggregate of the aggregate is 50 vol% or more, and a volume fraction of the aggregate in the total volume of the hydrated solidified body is 55 vol% or more.
The hydrated cured product of the present invention is excellent in fatigue durability. The reason for this is considered as follows.
The hydrated cured product "fatigue" due to repeated application of mechanical stress, and cracks and the like occur. The hydrated cured product of the present invention is expected to have excellent fatigue durability because it is appropriately filled with an aggregate and exhibits an action of preventing the generation and the development of cracks.
The hydrated cured body of the present invention is excellent in fatigue durability and therefore can be suitably used as, for example, harbor civil engineering materials, roadbed materials.
Hereinafter, the hydrated cured product of the present invention will be described, and a method for producing the hydrated cured product of the present invention will also be described.
[ aggregate ]
The aggregate used in the present invention (hereinafter, referred to as "aggregate in the present invention" for convenience) contains steel-making slag. In addition to the steelmaking slag, the aggregate in the present invention may also contain: previously known natural crushed stones and mountain sands; blast furnace slow-cooling slag, blast furnace water granulated slag fine aggregate (for example, aggregate prescribed in JIS A5011-1 "slag aggregate for concrete-part 1: blast furnace slag aggregate", etc., wherein, it may be any other than JIS); examples of the recycled aggregate for concrete include aggregates specified in JIS a 5021 "recycled aggregate for concrete H", JIS a 5022 "concrete using recycled aggregate M", and JIS a 5023 "concrete using recycled aggregate L", and the like, and may include other than JIS.
From the viewpoint of effective utilization of the steel-making slag, the volume ratio (volume ratio) of the steel-making slag in the aggregate in the present invention is preferably 50 volume% or more, more preferably 75 volume% or more, and still more preferably 100 volume%.
As the steel-making slag, not only slag generated in a converter, an electric furnace, a torpedo car, or the like, but also slag pretreated with molten iron, slag generated during stainless steel refining and containing t.cr of 0.5 mass% or more, and the like can be used. The steel-making slag may be etched, and the steel-making slag preferably has a water immersion expansion ratio of 0.5% or less, regardless of the etching method. It is also possible to use the steel-making slag subjected to the air-crushing treatment as a part of the steel-making slag, although the cost becomes high.
Aggregates are classified into fine aggregates and coarse aggregates. Such as JIS A0203: 2014, fine aggregate is aggregate which passes through a 10mm mesh screen and passes through a 5mm mesh screen at least 85% (by mass) (simply referred to as aggregate of less than 5 mm). On the other hand, the coarse aggregate is an aggregate which is retained in a 5mm mesh sieve at 85% by mass or more (simply referred to as an aggregate of 5mm or more).
< maximum dimension >
The maximum size of the aggregate in the present invention is 5mm or more and 60mm or less. Accordingly, the aggregate in the present invention contains at least coarse aggregate.
Here, the maximum size of the aggregate is defined as JIS a 0203: 2014 is a size represented by a nominal size of a sieve having the smallest size among sieves through which 90% or more (by mass) of the aggregate passes.
The relationship between the nominal size and the mesh opening (sieve opening) is described in JIS a 1102: 2014. and JIS Z8801-1: 2006. JIS Z8801-2: 2000 and JIS Z8801-3: 2000, for example, a nominal size of 40mm corresponds to a mesh size of 37.5 mm. Thus, for example, a steel-making slag having a maximum size of 40mm means the following steel-making slag: more than 90 mass% of the steel-making slag passes through the 37.5mm mesh size, and less than 90 mass% of the steel-making slag passes through the 31.5mm mesh size.
The maximum size of the aggregate in the present invention is preferably 10mm or more and 60mm or less because the fatigue durability of the hydrated cured body of the present invention can be further excellent.

The volume fraction of the aggregate was calculated as follows. First, the volume fractions of the materials such as water, aggregates (coarse aggregates and fine aggregates), binder, and air constituting the hydrated solidified body are determined. Next, a stirring test was carried out in a formulation calculated based on the volume fraction and density of each material (Japanese: り Japanese bench infusion test). After the stirring, the amount of air (unit: volume%) in the hydrated solidified body was measured, and the actual volume fraction of each material including the aggregate was calculated.
The volume fraction of the aggregate in the present invention is preferably more than 55 vol%, more preferably 57 vol% or more, because the fatigue durability of the hydrated cured product of the present invention can be further improved.
On the other hand, the upper limit is not particularly limited, and is, for example, 80 vol% or less, preferably 75 vol% or less.
< Fine aggregate fraction (s/a) >
