Description
Technical field
The present invention relates to a kind of early-strength function grinding aids, belong to building material technical field, it is low to be mainly used in clinker
The compound system of volume mixture cement.
Background technique
Cement refers to powdery hydraulicity inorganic coagulation material, at slurry after cement plus water stirring, can harden in air or
Person is preferably hardened in water, and can the materials such as sandstone are cemented together securely, using lime and the cementing rubble of volcanic ash
Manufactured concrete, not only intensity is higher after hardening, and can also resist the erosion of fresh salt water, and for a long time, cement is made
For a kind of important cementitious material, it is widely used in the engineerings such as civil construction, water conservancy and national defence, cement is divided by purposes and performance
General-purpose cement, cement special and characteristic cement, general-purpose cement refer to the cement that general civil construction project generallys use, dedicated water
Mud refers to the cement of the special purposes such as oil-well cement and road silicate cement, and characteristic cement refers to lumnite cement and swollen
The performances such as swollen sulphate aluminium cement cement more outstanding.Existing cement in use mainly using cement grinding aid into
Row is used in compounding, and cement grinding aid refers in the grinding process of clinker, and a small amount of additional substance is added, and can significantly mention
High mill efficiency reduces energy consumption, and does not damage the chemical addition agent of cement performance.Powder can be greatly lowered in cement grinding aid
The Electrostatic Absorption bag ball phenomenon formed during mill, and the coalescence again that can reduce the ultra-fine grain formed in grinding process becomes
Gesture, cement grinding aid can also significantly improve cement fluidity, improve the grinding effect of grinding machine and the grinding efficiency of powder concentrator, thus
Grinding energy is reduced, there is lower compacting coalescence trend using the cement that grinding aid produces, thus be conducive to the handling of cement,
And the wall built-up phenomenon of cement bunker can be reduced.Existing cement is mainly clinker-low-dosage mixture system, low-dosage mixture
Early activity is lower, the volume of mixture is improved in cement system, it is necessary to consider the loss of early strength, existing grinding aid
Early strong effect is poor in use for agent, therefore in order to meet early strength, the ratio that mixture adds in existing cement
Lower, the production cost increases for cement, and existing grinding aid formula composition is complicated, and production cost is higher, and economic benefit is difficult
To be guaranteed, it is not able to satisfy the needs that building uses.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of compositing formula advantages of simple, and grinding-aid effect is good, effectively mention
High mill efficiency reduces grinding energy, and can improve cement early strength, and early strong effect is obvious, meets building and uses needs
Early-strength function grinding aid.
In order to solve the above-mentioned technical problem, technical solution of the present invention is: a kind of early-strength function grinding aid,
It is characterized by: the early-strength function grinding aid includes water, diethanol monoisopropanolamine (DEIPA), sodium tripolyphosphate
(STPP), the parts by weight of molasses and propylene glycol, each constitutive material are as follows: 60 parts -80 parts of water, diethanol monoisopropanolamine
(DEIPA) 0 part -20 parts, 0 part -20 parts of sodium tripolyphosphate (STPP), 0 part -20 parts of molasses, 0 part -5 parts of propylene glycol.
Further, the early-strength function grinding aid includes the raw material of following weight parts: 70 parts of water, diethanol list isopropyl
10 parts of hydramine (DEIPA), 15 parts of molasses, 5 parts of propylene glycol.
Further, the early-strength function grinding aid is used in compounding with cement in use, and early-strength function helps
The mass ratio of grinding agent and cement is 1:1000.
Further, the water that the early-strength function grinding aid includes is deionized water.
Further, the cement includes clinker, gypsum, lime stone and mixture, and the parts by weight of each constitutive material are as follows:
75 parts -80 parts of clinker, 5 parts of gypsum, 5 parts of lime stone, 10 parts -15 parts of mixture, the mixing package containing flyash, gangue and
One of slag is a variety of.
Compared with prior art, the present invention brought beneficial effect is: early-strength function grinding aid composition of the present invention is matched
Square advantages of simple, grinding-aid effect is good, effectively improves mill efficiency, reduces grinding energy, and can improve cement early strength, early strong
Effect is obvious, meets the needs that building uses, and the mixture in cement of the present invention is using one in flyash, gangue and slag
Kind is a variety of, and the early activity of this kind of mixture is lower, after being added to early-strength type function grinding aid, can be applicable in
In the lower a variety of mixture additions of early activity, early-strength type function grinding aid can overcome the damage of early strength
It loses, while the grinding-aid effect and cement early strength for ensuring cement, the mixture volume in cement can be improved, reduce water
The production cost of mud, and have more than needed more cement for later strength, the low mixture of early activity in cement can be improved
Volume can not only reduce production cost, moreover it is possible to which the balance for realizing cement early strength and later strength utilizes above-mentioned a variety of groups
The compound use of part may be implemented grinding aid and early powerful superposition, can improve cement early strength and grinding aid be wanted
It asks, on grinding-aid effect, the cement for adding early-strength function grinding aid of the present invention is compared with the cement for being not added with grinding aid, compares table
Area improves 9m2/kg-18m2/ kg, tails over R45μm1.6%-2.3% is reduced, grinding-aid effect is obvious, and in early strength, addition is originally
The cement of invention early-strength function grinding aid is compared with the cement for being not added with grinding aid, and 3 days intensity of cement improves 1.2MPa-2.4
MPa, enhancing degree is 10% or so, and the early strength of low-clinker cement can achieve the early strength of high clinker cement, benefit
With early-strength function grinding aid of the present invention is added, early strength caused by clinker reduction by 5% in cement can be compensated and lost, and
It is smaller to 28 days intensity effects of cement to add early-strength function grinding aid of the present invention, intensity effect controls within 4%, using this
The early-strength function grinding aid of invention, for the cement of phase homogenous quantities, the mass ratio of early-strength function grinding aid and cement is 1:
1000, grinding aid additive amount of the invention is few, and performance is stablized, and grinding aid is early strong high-efficient, cement-grinding aid compounding cost compared with
It is low, meet the needs that building uses.
