Pour a proper amount of clean water into the bucket, turn on the agitator and slowly add a bag (it is better to add it within 1 minute) while stirring.
Pour out the mixed products, spread them evenly, and control the thickness with a special tooth scraper.
3.
If it is a smooth base, it is recommended to conduct chiseling or roughening treatment.
The strength of base course concrete before construction must be ≥ C20.
3.
When the surface is not sticky, self leveling construction can be carried out.
During small area or highway construction, small electric agitators (200~500 rpm) can be used for mixing in barrels, and complete packing materials shall be used for each mixing; In case of large area construction, high-speed mixer can be used for mixing and mortar pumping.
4.
The base course concrete surface shall be watered and wetted to ensure that there is no adhering water in the front layer.
2.
▼ Click the business card to pay attention to ▼ I.
When using, mix it evenly according to the proportion of EC-1: water: cement: fine sand=1:1:1:1, and then paint or spray it on the base surface.
2.
2、 Interface treatment 1.
The self leveling construction shall be carried out 21 days after the construction of the new ordinary cement concrete base, and 7 days after the completion of the new sulphoaluminate cement concrete base.
The reference dosage is 1.6kg/m2/mm.
4、 Pouring and leveling 1.
The reference dosage of EC-1 is 0.2 ～ 0.3kg/m2.
The mixed products shall be used up within 35 minutes.
Use the air release roller to gently roll to eliminate the air bubbles generated during mixing.
Base course treatment 1.
The temperature of mortar shall be kept above 5 ℃.
3.
After it is still for about 1 minute, stir again until it is even and free of lumps.
The uneven places, cracks and holes should be treated and leveled in advance, and then the scattered debris on the base surface should be removed.
The surface must be hard, flat and clean.
The construction personnel can wear nail shoes to enter the construction ground, and use the tooth scraper to scrape the mortar surface to eliminate the unevenness of the dumping joint and maintain the required thickness.
Outstanding articles in the past: Why is it unsafe to accept concealed works when there are too many beam reinforcements? It is difficult to make mistakes when 67 items are done in place.
Stir for 4-5 minutes.
2.
When are 10d, 12d and 15d used to connect 8 types of reinforcement on the construction site with 4 types of reinforcement,.
3、 Mixing 1.
5、 Curing is not required under normal temperature.
2.
Heavy traffic ground shall be cured for 3 days before passing.
In cold conditions, warm water (no more than 40 ℃) should be used for mixing.
The construction thickness of this product is ≥ 3mm, and the one-time construction thickness is 3-30mm.
In case of high or low temperature, watering or covering wet gunny bags, straw mats and other measures shall be taken after initial hardening for 1 to 3 days.
Animation simulation of masonry structure construction process is used to simulate the common data of reinforcement works.
It is recommended to use EC-1 surface treatment agent.
