Description
Technical field
The present invention relates to the Accessory Members of public works, particularly a kind of have a pavement bricks 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 again pavior brick, 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 must have its basic training with, fully expanding new additional function has been that trend becomes, Patents and document quite more than.Such as, aspect curb: CN201020116745 (a kind of highway roadside stone), CN200920222398 (a kind of non-watertight road edge stone) disclose curb hollow, can Accumulated Rainwater; CN02289404 (artificial kerbs), CN01138152 (coloured curb and particular manufacturing craft and manufacture method) and CN00229822 (colour bright curb, flower bed stone) disclose the concrete curb with decorative effect; CN02264059 (solar energy luminous curb) discloses a kind of Luminous curb that can be used as traffic sign; Closing aspect the concrete pavement bricks: a kind of concrete road pavement brick (Quan Peng with specific function is positive male etc., building block and building block building, 01 phase in 2011) introduced a kind of pavior brick with snow melting function; Remove NO
XPavior brick (paddy Zhang Zhao, Building Shanghai science and technology, 02 phase in 1999) introduced the pavior brick that in concrete, adds photocatalyst degraded automobile exhaust pollution thing; The colorful water-permeable brick has been introduced in the development of polychrome concrete road pavement brick and ecological permeable bricks and application (Zhu Zhirong, building block and building block building, 03 phase in 2005).
In the humidity of south China, shady highway section, it not is to rarely have that moss vegetates, and curb and pavement bricks growth moss also are seen everywhere.Namely affect attractive in appearancely after the moss growth, more can make troubles to walking, also may cause to slip when serious and get injured by a fall event.Therefore, allow 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 pavement bricks that can prevent the moss growth, this pavement bricks can effectively prevent the moss growth.
For achieving the above object, technical scheme of the present invention is: a kind of concrete pavement bricks that can prevent the moss growth, it is characterized in that it is prepared from by concrete component and the rare earth compound of pavement bricks, the add-on of rare earth compound be pavement bricks concrete component quality 4.5 * 10
-3%～31.5 * 10
-3%.
The concrete component of described pavement bricks comprises cement, flyash, sand, high-performance water reducing agent and water, wherein, cement: flyash: sand=1: 1.0: 1.5, water ash (ash refers to " cement adds flyash ") mass ratio 0.3, the add-on of high-performance water reducing agent is 0.7% of cement, flyash total mass.
Cement is PO42.5 cement; Flyash is fraction coal ash not; Sand is coarse sand and medium sand, its medium coarse sand 70wt%, medium sand 30wt%, coarse sand fineness modulus 3.5, medium sand fineness modulus 2.6.
High-performance water reducing agent is high performance water reducing agent of polyocarboxy acid (water reducer can be various commercial water reducers).
Described rare earth compound is ceric sulfate (Ce (SO

36H
2O), europium sesquioxide (Eu
2O
3) in any one or any two kinds mixture;
When rare earth compound was any one (single rare earth compound) in ceric sulfate, lanthanum nitrate, the europium sesquioxide: the add-on of ceric sulfate was 5.25 * 10 of concrete component quality
-3～15 * 10
-3%; The add-on of lanthanum nitrate is 12.0 * 10 of concrete component quality
-3～22.5 * 10
-3%; The add-on of europium sesquioxide is 7.5 * 10 of concrete component quality
-3～18.0 * 10
-3%;
When rare earth compound was any two kinds mixture in ceric sulfate, lanthanum nitrate, the europium sesquioxide: the add-on of ceric sulfate and europium sesquioxide mixture was 4.5 * 10 of 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 nitrate mixture is 13.5 * 10 of concrete component quality
-3～27.0 * 10
-3%, ceric sulfate: the mass ratio of lanthanum nitrate=4: 1～1: 1; The add-on of lanthanum nitrate and europium sesquioxide mixture is 18.0 * 10 of concrete component quality
-3～31.5 * 10
-3%, lanthanum nitrate: the mass ratio of europium sesquioxide=1: 1～1: 2.
Above-mentioned a kind of preparation method that can prevent the concrete pavement bricks 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 mix with other raw material in the concrete component, stir, obtain compound;
3) moulding: compound moulding, molding mode are that mould is built moulding, obtain preventing the concrete pavement bricks 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, be dissolved into it in water or form even suspension liquid, and then mix and stir mixed earth with the water that contains rare earth compound.
It is more obvious 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 substantially have the moss growth.Add more rare earth compound, still can reach same inhibition, but obviously unreasonable economically, so it is made as the upper limit.To get moss growth is had obvious inhibition as for lower limit, the addition when its growth area is not more than 30%.
The invention has the beneficial effects as follows: this pavement bricks can effectively prevent moss growth (its growth area is not more than 30%).
Embodiment
In order to understand better the present invention, further illustrate content of the present invention below in conjunction with embodiment, but content of the present invention not only is confined to the following examples.
In following examples, the concrete (concrete component) of producing pavement bricks all adopts following proportioning:
Cement: flyash: sand=1: 1.0: 1.5, water cement ratio 0.3, the add-on of high-performance water reducing agent is 0.7% of cement, flyash total mass.Cement is PO42.5; Flyash is fraction coal ash not; Sand is coarse sand and medium sand, its medium coarse sand 70wt%, medium sand 30wt%, coarse sand fineness modulus 3.5, medium sand fineness modulus 2.6; High-performance water reducing agent is high performance water reducing agent of polyocarboxy acid.Different embodiment just add the rare earth compound of different sorts and quantity on this proportioning basis.Molding mode is compression molding.
In order to estimate rare earth compound and composition thereof to the inhibition of moss growth, the testing method that following examples are taked and step are:
(1) makes respectively blank pavement bricks with being added with rare earth compound;
(2) inoculate moss kind liquid with spray method at the sample upper surface;
(3) (25 ℃ ± 2 ℃ of temperature, relative humidity 〉=85%, intensity of illumination 1000lx～3000lx), illumination every day 14 hours checked the surperficial moss growth of inoculation area on the 21st day postvaccinal sample to be put into the fixed temperature and humidity illumination box;
(4) the area less than 60% if blank sample surface moss grows is then thought and is not inoculated, and needs again test;
(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 less inhibition degree of this percentage ratio is higher, is fully not growth of 0 expression.
