Use Of Epoxy Grout Notes In Summer
Use of Epoxy Grout notes in summer
Summer temperatures are high, and easy to wind, the air is dry, so the construction of Epoxy Grout will have a certain impact. Therefore, in order to avoid these problems on the construction of the impact of summer use of Epoxy Grout when we must pay attention to the following questions
First of all, need to pay attention to the pouring, the template, steel, the second secondary Epoxy Grout grass to sprinkle water, cooling, but also reasonable sub-stratification, so that the old and new pouring interval shorter. If a higher slump of concrete Epoxy Grout mixture is required, a superplasticizer should be used and the slump of the mixture produced by some superplasticizer can be maintained for 2 hours.
Second, the need to control the delivery time, transport issues should be shortened to the external transport time, control the transport distance. In the Epoxy Grout to reach the site should be immediately after the material unloading and pouring, to avoid the residence time is too long cause a greater loss of slump. When the internal conveyor is pumped, the conveyor pipe should cover the damp cloth.
Finally, the aggregate and mixing water should be avoided by direct sunlight, which can be sprinkled to cool the aggregate. Mixing water is best to use well water, such as with a storage tank, should avoid direct sunlight. Sprinkle water into the aggregate pile to reduce the temperature of the concrete Epoxy Grout aggregate, should avoid the Epoxy Grout mixture temperature exceeds 30 ℃, if necessary, add ice to reduce the secondary Epoxy Grout mixture temperature.
What are the commonly used grouting methods for Epoxy Grout? As the Epoxy Grout has a strong liquidity, so for plugging, the effect is no better. However, today's focus for everyone to introduce several grouting methods, we hope that after the use of Epoxy Grout to help.
The first kind is the high funnel method, the high funnel method is the Epoxy Grout construction, only the flow of Epoxy Grout can not meet the requirements, the use of grouting to improve the potential difference to meet the grouting requirements of the method. The method is suitable for large equipment base (side length of more than 3m) grouting. At this point, in the equipment base to arrange the appropriate vent, the hole diameter of not less than 30mm. This grouting method should also be used for equipment with trenches under the box base and base.
Another is the self-weight method, is in the Epoxy Grout construction, the use of its good mobility characteristics, in the range of free flow within the grouting to meet the grouting requirements of the method used in the base of the equipment under the flat surface of the equipment Grouting.
Finally, there is a method of pressure grouting, pressure grouting method is in the Epoxy Grout construction, the use of grouting pressurization equipment to meet the grouting requirements of the method. The method is suitable for complex structure and anti-Epoxy Grout, this time to use grouting pressurization equipment.
Epoxy Grout in the coating? Epoxy Grout in the Epoxy Grout floor construction process of the key steps, the construction will directly affect the quality of Epoxy Grout floor quality
(1) batch scratch thick quartz mortar layer: the first Epoxy Grout in the main agent to stir evenly, according to the proportion of the main agent and curing agent mixed, stir evenly, when mixing the curing agent from the main agent of the barrel down To avoid uneven mixing of materials. After mixing, with the appropriate amount of 60 mesh -80 mesh rough quartz sand, scraper scraper process used to fill the flat surface.
(2) batches of fine quartz mortar layer: in a good mix of Epoxy Grout in the amount of 100 mesh-120 mesh fine quartz sand, the same batch of approved scraping knife, and further increase the resistance of the coating and impact resistance performance.
According to the design thickness of the floor can be repeatedly scraping repeated (1) (2) Road process, to be mortar in the coating after curing grinding, clean and clean.
