Abstract
The invention discloses an engineering structure fast-hardening lost circulation additive and the preparation method thereof. The lost circulation additive is produced into power by mechanical agitation of silicate, silicon powder, mineral chemical addition agents, natural quartz powder, calcite powder and other auxiliary agents, then the lost circulation additive is added with a proper amount of water and is adjusted into even paste, and then rapid solidification and instant leak stopping and water sealing can be archived. The powdery lost circulation material has excellent comprehensive performance, high early strength and good frost resistance, permeability resistance and sulfate resistance, especially has outstanding hydrophobicity, durability and bonding strength, and is suitable for the leak maintenance of underground buildings, hydraulic structures, tunnels, culverts or other concrete and brick-stone structures. The lost circulation additive has the advantages that the required raw materials are easy to be acquired, the manufacture is simple and convenient, the workability is good, the lost circulation additive can be adjusted only by water, and the patching operation can be accomplished within 3 to 5 minutes, so as to facilitate popularization and application.
Description
Technical field
The present invention relates to a kind of cement, relate to the hard leak stopping its preparation method of ordinary Portland cement or silicate cement speed in particular.
Background technology
In general, concrete works accounts for half of whole civil engineering greatly, still since construction process in thin be other reasons, caused leak or the crack in the engineering.Therefore, special engineerings such as various waterproof, leak stopping, repairing can have a kind of rapid mending-leakage material, otherwise can cause the loss that can't retrieve to engineering.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of silicate cement fast-hardening plugging agent and preparation method thereof.Fast-hardening plugging agent of the present invention, also form by following substances by following weight percent:
Silicate cement: 30%-65%
Silica powder (325 order): 15%-35%
Zeolite group mineral additive: 6%-20%
Silica flour (325 order): 4%-10%
Stablizer: 0.1%-2%
Calcite in powder (400 order): 2%-5%
The preparation method of this project structure fast-hardening plugging agent is characterized in that: described step is:
In a, the silicate cement adding mechanical stirrer with 30%-65%;
B, the silica powder of the zeolite group mineral additive of the silica flour of 4%-10%, 6%-20%, 15%-35% mixed after, mix thoroughly with the speed of 300-4 commentaries on classics/min ..;
C, add the 0.1-2% stablizer again, the 2%-5% calcite in powder stirs promptly with the speed of 300-450 commentaries on classics/min
Embodiment:
Embodiment 1, take by weighing 65 kilograms of silicate cements, 10 kilograms of silica flours, 10 kilograms of zeolite group mineral additives, 15 kilograms in powder, after dropping into agitator and stirring, add 1.0 kilograms stablizer, 1.0 kilograms calcite in powder stirs
Embodiment 2, take by weighing 30 kilograms of silicate cements, 8 kilograms of silica flours, 20 kilograms of zeolite group mineral additives, 35 kilograms of stone flours, after dropping into agitator and stirring, add 2.0 kilograms stablizer, 5.0 kilograms calcite in powder continues to stir
Embodiment 3, take by weighing 65 kilograms of silicate cements, 4 kilograms of silica flours, 6 kilograms of zeolite group mineral additives, silica powder kilogram, after dropping into agitator and stirring, add 2.0 kilograms stablizer, 2.0 kilograms calcite in powder continues to stir.
The plugging agent excellent combination property, the early strength height that adopt the inventive method to produce, frost resistance impermeability, sulfate resistance can be good, particularly hydrophobic nature, weather resistance, cohesive strength are given prominence to, and are applicable to underground structure, hydraulic structure, tunnel culvert or the repairerment of other concrete brick stone structure seepage.
That this material feedstock is easy to get, makes is easy, application property good, only needs to be in harmonious proportion with clear water, and 3-5 divides kind just can become patch work, is beneficial to promote the use.
