Abstract

The invention discloses anti-corrosion cement and an application thereof. The anti-corrosion cement comprises the following raw materials by weight: 280-720 parts of cement clinker, 80-210 parts of high-molecular polymer, 50-150 parts of calcium sulfate, 15-45 parts of coal ash, and 30-60 parts of a stabilizer. The anti-corrosion cement is prepared by the steps of mixing, pre-heating, decomposing, calcining, grinding and homogenizing. The composition sources of the anti-corrosion cement are extensive, the high-molecular polymer is added to the cement clinker for preparing the anti-corrosion cement, and the process is simple. Compared with other cement, the anti-corrosion performance of the prepared annular concrete pole and other cement product is stronger, and the abrasive resistance is good.

Description

A kind of corrosion-resistant cement and its application
Technical field
The present invention relates to a kind of cement, specifically a kind of corrosion-resistant cement and its application, belong to building material field.
Background technology
Cement is a kind of powdery hydraulicity inorganic coagulation material.Cement is in powder, becomes slurry after the stirring that adds water, can be in sky Harden in gas or preferably harden in water, and can be cemented together securely for the materials such as sand, stone.The history of cement can chase after Trace back the mixture of roman's Calx used in architectural engineering and volcanic ash.The mixture of early stage Calx and volcanic ash with Modern lime pozzolanic cement is much like, the concrete made with its cementing rubble, and after hardening, not only intensity is higher, but also The erosion of fresh water or brackish water can be resisted.British j. Parker fires a kind of brown cement with marl within 1796, claims Luo Mashui Mud or Parker's cement.British j. A Sipuding limestone in 1824 and clay are fired into cement, the color after hardening and English On Glan island, the local stone for building of Portland is similar, is named as Portland cement, and achieves patent right.Long-term with Come, cement, as a kind of important Binder Materials, is widely used in the engineerings such as civil construction, water conservancy, national defence.With World Economics Fast development, building, building industry also correspondingly flourishes.Cement, as a kind of most basic building material, has not The cement of congenerous or several functions is developed, for example alumina cement, special cement etc..Although but current cement is multiple Various, but it is as the change of cement purposes, novel concrete still has the huge market demand.
Under general use condition, general-purpose cement has preferable corrosion resistance in itself.But it is under corrosive environment, many The concrete works that general-purpose cement is formulated just occurs getting up early to damage or even thoroughly destroy in a short time, and the engineering life-span much reaches not To design life.Acid and acid water, salt, alkali and alkaline water are all easily caused cement corrosion and damage.
Content of the invention

Preferably, a diameter of 0.08 ~ 0.1mm of clinker that in step s4, grinding becomes.
Described stabilizer be cement stabilizing agent, can be polymer-type can also be bentonite type.
The corrosion-resistant cement composition ingredient origin of the present invention is extensive, by clinker interpolation high molecular polymer preparation Become, operation is simple, it is higher that obtained annular concrete electric pole and other cement products compare other cement decay resistances, with When, there is good wearability.
The corrosion-resistant cement of the present invention can adopt c50 concrete, c60 concrete, the match ratio of c65 concrete, prepares concurrent；Also may be used With according to c50 concrete, using water: cement: sand: stone: the match ratio of water reducer=0.36:1:1:2.3:0.3% or according to c60 Concrete, using water: cement: sand: stone: the match ratio of water reducer=0.36:1:1.1:2.3:0.5%, produce cable channel cover plate water Mud product.
When the corrosion-resistant cement of the present invention is used for producing cable channel cover plate, the preparation of concrete adopts order below: first plus Enter sand, be subsequently adding cement, add 2/3rds water, stir 30s, finally add stone and remaining water, water reducer； During concrete cast, it is vibrated to vibrator closely knit after filling concrete, and the concrete stirring time once is less than 45min.
When the corrosion-resistant cement of the present invention is used for producing concurrent, the preparation of concrete adopts order below: first plus Enter sand, be subsequently adding cement, add 2/3rds water, stir 30s, finally add stone, remaining water, water reducer； During concrete cast, in top end, 1 meter about should be filled up concrete and insert real, at half meter of butt, suitably few should note or do not note concrete.
