Product description of ultra-fine cement grouting material
Ultra-fine cement grouting material
Ultra-fine cement grouting material is composed of high-strength ultra-fine cement, expansion agent, slag, etc. A new generation of inorganic rigid ultra-fine grouting materials refined with special equipment.
1. The product is excellent
, non-toxic, odorless, has no pollution to groundwater and the environment, and is an environmentally friendly grouting material
. There is no shrinkage when the slurry solidifies, and the stone has high strength and good durability. It does not age, has good impermeability
and good slurry fluidity. The specific surface area of the material is above ㎡/㎏ and below the average particle size, so it has high stability and groutability
and the slurry setting time can be Adjust according to project needs
The slurry construction process is simple, easy to operate, and can be used on a large scale.
2. Application scope
． Irrigation of cracks in the dam body and dam foundation in water conservancy projectsbr/>． Construct underground waterproof curtains to cut off seepage water sources and achieve overall anti-seepage plugging.br/>． Reinforce and improve the mechanical strength of soft soil and rocks, repair concrete structures and restore their integritybr/>. Correct the cracking and tilting of dams and high-rise buildings caused by uneven settlement caused by unstable strata. Grouting for subsidence of roads, bridges, airport runways, etc. ． Pretreatment before excavation of various underground buildings, as well as hole protection and wall solidification in complex formation drilling during geological drilling, surge prevention and leakage prevention, etc.br/>. Consolidation of sand in the quicksand layer of complex strata and consolidation of silty soil layers.
3. Technical indicators
. The physical properties of the grouting material (measured under ℃ conditions) Ultra-fine cement grouting material can be processed according to the special requirements of customers
. Grouting under different water-cement ratios The strength of the grouting material is the same as that of cement. The fluidity and permeability of the grouting material increase with the increase of the water-cement ratio, but the setting time increases with the increase of the water-cement ratio. The strength increases with the increase of the water-cement ratio. Therefore, the water-cement ratio should be reduced as much as possible on the premise of meeting the construction requirements.
4. Packaging and Storage
Packed in plastic woven bags, net weight kg/bag, shelf life: 1. Must be stored in a dry and ventilated room, the woven bag should be sealed, and pay attention to moisture and freezing.
5. Instructions for use
For gap spaces of different sizes. Different soil geological environments, different grouting basic conditions, and different strength indicators require determining the appropriate water-cement ratio (usually the range of the water-cement ratio of the grouting material is), and use an electric mixer to stir until uniform. Then pour the grout into the grouting bucket
, dock and fix the delivery pipe mouth of the grouting machine with the grouting nozzle fixed on the foundation in advance, turn on the power of the grouting machine, and open the valve for grouting. And control the grouting pressure within a certain range (usually within the range. Different basic conditions, different water-cement ratios, the required grouting pressure is different. If the grouting pressure is too high, splitting grouting may occur and the grouting cannot be uniform. Penetration. If the grouting pressure is too small, it cannot penetrate into the fine spaces)
. Close the grouting holes after the grouting is completed
. When the grouting area is large, segmented grouting can be used.
