Description
Technical field
The invention belongs to chemical building material field more particularly to a kind of efficient cracking resistance cement soundness agents.
Background technique
Currently, 70% or more cement is shaft kiln production, the disadvantage of the generally existing stability difference of these cement qualities causes
The bad reason of cement stability has very much, mainly there is following three kinds: free calcium oxide contained in clinker is excessive, institute in clinker
The free magnesium contained is excessively or the gypsum of incorporation is excessive.Free calcium oxide or magnesia contained in clinker are all burning,
Curing is very slow, is just cured after hardening of cement, this is the chemical reaction of a volume expansion, can cause non-uniform volume
Variation, makes Behavior of Hardened Cement Paste crack.When gypsum addition is excessive, after hardening of cement, it also be will continue to and solid drated calcium aluminate
Reaction generates high sulfur type hydrated calcium aluminate sulfate, and volume about increases 1.5 times, can also Behavior of Hardened Cement Paste be caused to crack.It is main in general
Be due to excessively high containing f-CaO caused by, general f-CaO content should be≤6%, as with these exceeded stabilitys differences
The building that cement is built, after some months or several years, the danger for often having cracking even to collapse, this will make to architectural engineering
At great hidden danger.Therefore, the content for how reducing free calcium CaO in cement, it is in the urgent need to address for improving the quality of cement
The problem of, current 80% manufacture of cement belongs to small manufacture of cement, due to production technology etc., free oxygen in small manufacture of cement
It is generally all very high to change calcium, it is unqualified to will cause out mill cement stability sometimes.Cement is mainly taken to overstock the method for storage at present,
Contact cement and air, to reduce the content of free calcium oxide, but still have large quantities of cement because stability it is unqualified caused by grow
Phase overstocks or as waste product.And at present to the undesirable processing method of cement stabilizing, it usually takes to add in cement and stabilize
Agent improves its stability, and cement stability is also known as " cement volume stability ".One of important indicator of cement quality.Reflection
The uniform situation of cement volume change in condensation hardening process.As contained excessive free lime, magnesia or three in cement
Non-uniform volume change can occur when condensing hardening for sulfur oxide, and it is existing the unstabilities such as cracking, bending, crisp and collapse occur
As." common portland cement " (GB1751007) regulation, cement stability are qualified using boiling process detection." cement normal consistency
Water consumption, condensation when ask, the stability method of inspection " (GB/T 1346-2011) regulation, cement stability can be used Lei Shi method and
The measurement of test cake method.The former is that the relative movement of test point characterizes it after boiling is boiled in Lei Shi folder by measurement cement normal consistency net slurry
The degree of volume expansion；The latter is that the profile variation situation after being boiled by observation cement normal consistency net slurry test cake boiling characterizes its body
Product stability.Cement soundness agent is during cement applications, to improve or realizing auxiliary agent that various characteristics are added, such as plus
The fast dry and hard speed of cement, improve cement it is dry and hard after intensity or reducing cement water consumption, as a kind of chemical activator, cement
Additive can also improve concrete scroll and excite the hydration activity of each mixing material, to improve cement early strength and later period
Intensity, therefore a certain amount of cement soundness agent would generally be added finished cement is adjusted in carrying out cement production process
Performance, but stabilization agent can make it in use, be easy to produce crackle, and compression strength is low, it is also difficult to promote the use of.
