Abstract
The invention discloses masonry mortar. The masonry mortar is prepared from, by weight, 60 parts of ordinary Portland cement, 15-20 parts of fluidized bed combustion ash, 15-20 parts of fly ash and 5-10 parts of additives. The prepared masonry mortar is high in strength and not prone to cracking.
Description
Technical field
The present invention relates to a kind of masonry mortar.
Background technology
Masonry mortar is the mortar that brick, stone, building block etc. are bonded as masonry, and it plays a part transmission load, is the important component part of masonry. In the technology of preparing of tradition masonry mortar, many employing cement are as major gelled material, but due to the shrinkage of cement self, and cause the contraction of mortar. In existing improvement technique, there is employing fluidized bed combustion coal ash/slag to replace cement, by generating dilatancy product after fluidized bed combustion coal ash/slag aquation, there is dilatancy, improve the contractility of tradition masonry mortar. But adopt the masonry mortar insufficient strength that fluidized bed combustion coal ash/slag prepares, and easy to crack.
Summary of the invention
The invention aims to the defect solving exist in prior art, it is provided that the masonry mortar that a kind of intensity is higher, not easy to crack.
In order to achieve the above object, the invention provides a kind of masonry mortar, including the component of following weight proportion: Portland cement 60 parts, fluidized bed combustion coal ash/slag 15-20 part, flyash 15-20 part, additive 5-10 part.
Wherein, additive includes foaming agent and thickening agent; The weight ratio of foaming agent and thickening agent is 5:1.
Preferably, additive also includes carbon fiber; The weight ratio of carbon fiber and thickening agent is 1:1.
Carbon fiber length is 3-5mm.
Foaming agent preferably sodium dodecyl sulfate; Thickening agent optimization polypropylene amide.
The optimal component weight proportion of masonry mortar of the present invention is: Portland cement 60 parts, fluidized bed combustion coal ash/slag 20 parts, 20 parts of flyash, sodium lauryl sulphate 5 parts, polyacrylamide 1 part, 1 part of carbon fiber.
The present invention has the advantage that the present invention utilizes fluidized bed combustion coal ash/slag as extender compared to existing technology, it is to avoid cement autogenous shrinkage causes Mortar shrinkage; Utilize flyash to improve the stability of system, it is prevented that owing to the excessive expansion of fluidized bed combustion coal ash/slag causes mortar to ftracture simultaneously; Toughness and the cracking resistance of mortar is increased in conjunction with carbon fiber. The masonry mortar prepared, 28d comprcssive strength more than 35.0MPa, 28d rupture strength more than 8.5MPa.
Detailed description of the invention
Below in conjunction with specific embodiment, masonry mortar of the present invention is described in detail.
Embodiment one
Masonry mortar: Portland cement (PO42.5, PO52.5) 60 parts, fluidized bed combustion coal ash/slag 15 parts, 15 parts of flyash, sodium lauryl sulphate 5 parts, polyacrylamide 1 part.
The masonry mortar 28d comprcssive strength prepared is 37.0MPa, 28d rupture strength is 9.5MPa, free from flaw.
Embodiment two
Masonry mortar: portland cement 60 parts, fluidized bed combustion coal ash/slag 20 parts, 20 parts of flyash, sodium lauryl sulphate 5 parts, polyacrylamide 1 part, 1 part of carbon fiber.
The masonry mortar 28d comprcssive strength prepared is 42.0MPa, 28d rupture strength is 14.0MPa, free from flaw.
