Abstract
The invention relates to concrete road edge stones capable of preventing moss from growing, which are characterized in that the stones are prepared from a concrete component and a rare earth compound. The adding amount of the rare earth compound is 0.0045-0.0315% of the concrete component of the road edge stones by mass. The road edge stones can effectively prevent moss from growing.
Description
Technical field
The present invention relates to the attached member of public works, particularly a kind of have a curb that prevents moss growth function.
Background technology
The material of curb mainly contains two kinds: lithotome and concrete, along with the exhaustion of rock material resource and the raising of environmental protection consciousness, the application of concrete curb is more and more general.Pavement bricks is called pavior brick again, mainly contains two kinds of sintering pavior brick and concrete road pavement bricks, and the power consumption of sintering pavior brick is high.Therefore, under the development trend of energy-saving and emission-reduction, concrete road pavement brick has become main flow.
For concrete curb and pavement bricks, except that must have its basic training with, fully expanding new additional function has been that trend becomes, related patent U.S. Patent No. and document quite more than.For example, in Curb aspects: CN201020116745 (one kind of road Curb), CN200920222398 (one kind of permeable Curb) are disclosed hollow, rainwater can be pooled Curb; CN02289404 (artificial Curb), CN01138152 (Color Curb and special tooling and manufacturing methods) and CN00229822 (Curb bright color, flower beds, stone) discloses a decorative concrete curbs; CN02264059 (solar light Curb) discloses a method can be used as transport Curb luminous signs; shut concrete brick sidewalks in areas: a special feature of the concrete pavers (dog Peng Masao, etc. Building Block and Block Building, 2011 01) describes a function with snowmelt pavers; removal of NO
X of pavers (Gu Zhang Zhao, Shanghai Construction Science & Technology, 1999 02) introduced in the concrete added photocatalytic degradation of pollutants in automobile exhaust pavers; multi- colored concrete permeable brick pavers and Ecological Development and Application (Zhu Zhirong, Building Block and Block Building, 2005 03) describes the color permeable brick.
In the southern humidity of China, shady highway section, it not is to rarely have that moss vegetates, and curb and pavement bricks growth moss also are seen everywhere.Promptly influence attractive in appearancely after the moss growth, more can make troubles, also possibly cause to slip when serious and get injured by a fall incident to walking.Therefore, let curb and pavement bricks have anti-moss growth function concurrently realistic meaning is arranged.
Summary of the invention
The object of the present invention is to provide a kind of concrete curb that can prevent the moss growth, this curb can effectively prevent the moss growth.
For realizing above-mentioned purpose; Technical scheme of the present invention is: a kind of concrete curb that can prevent the moss growth; It is characterized in that it is prepared from the concrete component and the rare earth compound of curb, the add-on of rare earth compound be curb concrete component quality 4.5 * 10
-3%～31.5 * 10
-3%.
The concrete component of said curb comprises cement, sand, stone, high efficiency water reducing agent and water; Wherein, Cement: sand: the mass ratio of stone=1: 1.2: 2.5, water ash (ash refers to " cement ") mass ratio 0.42, the add-on of high efficiency water reducing agent is 1.2% of a cement quality.
Cement is PC32.5 cement;
Sand is medium sand, fineness modulus 2.6;
Stone is a ls matter rubble, particle diameter 3～8mm.
High efficiency water reducing agent is a naphthalene series high-efficiency water-reducing agent.
Described rare earth compound is ceric sulfate (Ce (SO
4)
24H
2O), Lanthanum trinitrate (La (NO
3)
36H
2O), europium sesquioxide (Eu
2O
3) in any one or any two kinds mixture;
When rare earth compound was any one (the single rare earth compound) in ceric sulfate, Lanthanum trinitrate, the europium sesquioxide: the add-on of ceric sulfate was 5.25 * 10 of a concrete component quality
-3～15 * 10
-3%; The add-on of Lanthanum trinitrate is 12.0 * 10 of a concrete component quality
-3～22.5 * 10
-3%; The add-on of europium sesquioxide is 7.5 * 10 of a concrete component quality
-3～18.0 * 10
-3%;
When rare earth compound was any two kinds mixture in ceric sulfate, Lanthanum trinitrate, the europium sesquioxide: the add-on of ceric sulfate and europium sesquioxide mixture was 4.5 * 10 of a concrete component quality
-3～12.0 * 10
-3%, ceric sulfate: the mass ratio of europium sesquioxide=2: 1～1: 2; The add-on of ceric sulfate and Lanthanum trinitrate mixture is 13.5 * 10 of a concrete component quality
-3～27.0 * 10
-3%, ceric sulfate: the mass ratio of Lanthanum trinitrate=4: 1～1: 1; The add-on of Lanthanum trinitrate and europium sesquioxide mixture is 18.0 * 10 of a concrete component quality
-3～31.5 * 10
-3%, Lanthanum trinitrate: the mass ratio of europium sesquioxide=1: 1～1: 2.
The above-mentioned preparation method that can prevent the concrete curb of moss growth, it comprises the steps:
1) choose raw material by said ratio,
2) rare earth compound is mixed with water in the concrete component, and then with the concrete component in other raw materials mix, stir, obtain compound;
3) moulding: compound moulding, molding mode are that mould is built moulding, obtain preventing the concrete curb of moss growth.
Because the addition of rare earth compound seldom; In order to obtain best anti-moss growth result; Preferably with rare earth compound to be added with mix and stir concrete water and mix, it is dissolved in the water or forms even suspension liquid, and then mix and stir mixed earth with the water that contains rare earth compound.
It is obvious more to increase the effect that suppresses the moss growth with rare earth compound and composition thereof addition, and therefore the addition upper limit of above-mentioned rare earth compound and composition thereof is when rare earth compound reaches this value, does not have the moss growth basically.Add more rare earth compound, still can reach same inhibition effect, but obviously unreasonable economically, so it is made as the upper limit.As for lower limit is to get the moss growth is had obvious inhibition effect, and its growth area is not more than 30% o'clock addition.
The invention has the beneficial effects as follows: this curb can effectively prevent moss growth (its growth area is not more than 30%).
Embodiment
In order to understand the present invention better, further illustrate content of the present invention below in conjunction with embodiment, but content of the present invention not only is confined to following embodiment.
In following examples; The concrete (concrete component) of producing curb all adopts following proportioning: cement: sand: the mass ratio of stone=1: 1.2: 2.5; Water ash (ash refers to " cement ") mass ratio 0.42, the add-on of high efficiency water reducing agent is 1.2% of a cement quality.Cement is PC32.5 cement.Sand is medium sand, fineness modulus 2.6.Stone is a ls matter rubble, particle diameter 3～8mm.High efficiency water reducing agent is a naphthalene series high-efficiency water-reducing agent.
Different embodiment just add the rare earth compound of different sorts and quantity on this proportioning basis.Molding mode is that mould is built moulding.
In order to estimate the inhibition effect of rare earth compound and composition thereof to the moss growth, testing method that following examples are taked and step are:
(1) makes blank and the curb that is added with rare earth compound respectively;
(2) inoculate moss kind liquid with spray method at the sample upper surface;
(3) postvaccinal sample is put into fixed temperature and humidity illumination box (25 ℃ ± 2 ℃ of temperature, relative humidity >=85%, intensity of illumination 1000 1x～3000 1x), illumination every day 14 hours, the 21st day surperficial moss growth of inspection inoculation area;
(4) the area less than 60% if blank sample surface moss grows is then thought and is not inoculated, and needs test again;
(5) account for the growing state that the percentage ratio of inoculating surface area is weighed moss with the area that the moss growth is arranged at last, the more little inhibition degree of this percentage ratio is high more, is 0 expression not growth fully.
