Description

A kind of Machine-made Sand cement mortar
Technical field
The present invention relates to a kind of cement mortar, more particularly to a kind of Machine-made Sand cement mortar.
Background technology
Current building mortar generally makees the aggregate of building mortar using river sand sandstone, because construction industry is rapidly sent out in recent years Exhibition, it is therefore desirable to substantial amounts of river sand.Due to destructive mining type and excessive exploitation, serious have impact on natural, ecological Environment and natural, ecological rule.Because the speed of industry hails exhibition, a large amount of discharges of industrial wastewater and urban domestic wastewater, river sand sand Stone is heavily contaminated, and exploitation river sand is used to build and will have a strong impact on the living environment of people and healthy.Therefore, A kind of mortar for being suitable for building and substituting river sand of exploitation is the task of top priority.
The content of the invention
It is an object of the invention to provide a kind of Machine-made Sand cement mortar, to river sand can be substituted for building.
The present invention is achieved through the following technical solutions:
A kind of Machine-made Sand cement mortar, including following weight portion component:
Further, the dispersing aid is in proportion 1~2.7 by Tissuemat E and macrogol ester:1 combines.
Further, a kind of Machine-made Sand cement mortar includes the component of following weight portion:620 parts of Machine-made Sand;Water 150 parts of mud;20 parts of calcium oxide;20 parts of calcium stearate;8 parts of emulsifying agent;10 parts of dispersing aid;20 parts of bentonite;Phthalic acid 1.15 parts of dibutyl ester;Wherein, dispersing aid is in proportion 1 by Tissuemat E and macrogol ester:1 combines.
Further, a kind of Machine-made Sand cement mortar includes the component of following weight portion:720 parts of Machine-made Sand;Water 225 parts of mud;15 parts of calcium oxide;15 parts of calcium stearate;6.5 parts of emulsifying agent;6 parts of dispersing aid;12 parts of bentonite;Phthalic acid 0.75 part of dibutyl ester;Wherein, dispersing aid is in proportion 1.9 by Tissuemat E and macrogol ester:1 combines.
In order to the present invention is better achieved, a kind of Machine-made Sand cement mortar includes the component of following weight portion:Mechanism 820 parts of sand;300 parts of cement;10 parts of calcium oxide;10 parts of calcium stearate;5 parts of emulsifying agent;3 parts of dispersing aid;5 parts of bentonite;It is adjacent 0.3 part of dibatyl phithalate;Wherein, dispersing aid is in proportion 2.7 by Tissuemat E and macrogol ester:1 combines.
In order to ensure effect, the Machine-made Sand is the rock particles that granularity is 0.08~2.5mm after rock is crushed.
The present invention compared with prior art, with advantages below and beneficial effect:
(1) mortar of the invention possesses the performance of river sand completely, river sand can be replaced to use under construction, therefore can prevent The living environment of resident and healthy is influenceed using the river sand being contaminated, while the exploitation that can also reduce river sand makes nature Ecological environment is protected.
(2) principal ingredients of the invention are Machine-made Sand and cement, and Machine-made Sand then derives from rock, and it is originated widely, Therefore rock feedstock source abundance and low cost, so that mortar cost of the invention is relatively low, and by component of the invention Can also cause that mortar of the invention meets the performance of river sand after cooperation, and then enable that mortar of the invention replaces river completely Sand.
Specific embodiment
The present invention is described in further detail with reference to embodiment, but embodiments of the present invention not limited to this.
Embodiment 1
A kind of Machine-made Sand cement mortar of the invention, including following weight portion component:620 parts of Machine-made Sand;Cement 150 Part;20 parts of calcium oxide;20 parts of calcium stearate;8 parts of emulsifying agent;10 parts of dispersing aid;20 parts of bentonite;Dibutyl phthalate 1.15 parts.The dispersing aid is in proportion 1~2.7 by Tissuemat E and macrogol ester:1 combines, in the present embodiment Dispersing aid be in proportion 1 by Tissuemat E and macrogol ester:1 combines.
The Machine-made Sand that the present invention is used is the rock particles that granularity is 0.08~2.5mm after rock is crushed, i.e. the present invention makes Machine-made Sand derives from rock feedstock, and rock source is widely, therefore rock feedstock source abundance and low cost, so that So that mortar cost of the invention is relatively low.Due to rock particles rough surface, the cement mortar dispersive property being made is poor, and river sand Sand grain surface unusual light, dispersive property is very good when the cement mortar being made is constructed.Therefore, added in mortar of the invention The components such as emulsifying agent, dispersing aid and dibutyl phthalate, to ensure that the cement mortar that Machine-made Sand is made has river sand Equal good dispersive property when the cement mortar being made is constructed.Form one is the performance of the Machine-made Sand cement mortar of the present embodiment Index parameter experimental data.
