First, the material
The variety, specification, color, pattern and grade of the square brick shall conform to the design requirements; the product quality shall conform to the national standard of the square brick, and the product certificate shall be attached; the product for cornering, threshing, cracking or damage shall be eliminated. It is strictly forbidden to disperse in bulk at the construction site and it is strictly forbidden to get wet
Auxiliary materials: cement, sand, water, etc.
Second, the tool
Sieves, window screens, wooden trowels, iron trowels, small ash shovel, straight wood bars, level feet, ink fountains, eight-foot ruler, support plate, hardwood clapper, broom, watering can, nutcracker, wooden hammer, wire, large Wire hammer, steel sheet cutting, diamond cutting machine and ash mixing tools.
Third, the construction instructions
1. When opening the box, please look for the product specifications, size, color number, etc.
The paving effect puts the same product together, and does not mix different products together (unless consciously pursues a special effect).
2. Before the paving, first try the paving on the ground, and determine the brick-laying method according to the paving form. If the brick surface has a pattern or a directional pattern, the product should be laid in the direction shown in the figure for the best effect; The square tiles with different sizes and sizes are distinguished by the labels, and the adjacent color numbers and sizes can be used after the same color number or size is used.
3. When pre-laying, pull two vertical limits on the treated ground and use the horizontal ruler to level.
4, clean up the site, first sprinkle the right amount of water to facilitate construction; it is recommended to mix 325# cement and sand into a mortar ratio of 1:3 (mixed mortar is best not to exceed 200#, otherwise the mortar mark is too high, resulting in late The solidification shrinkage stress is not uniform.)
5, square bricks according to the design size of the line, the need to reserve the seam when marking, the gap is generally 5mm-12mm is appropriate.
6. The paving should be carried out after the base is solidified. During the paving process, the hand should be gently pushed and put to balance the brick bottom and the paving surface, so that the air bubbles can be easily discharged, and then the brick surface can be tapped with a wooden hammer to make the brick bottom comprehensive. Eat the pulp to avoid the phenomenon of empty drums; then use the wooden hammer to knock the brick surface to the level, and measure with the level to ensure the level of the square brick paving.
Paving effect 7, side paving, side jointing, jointing with cement mortar, can also add color additive joints according to demand. The width of the joint is 5-12mm and the depth is 2mm. The solid base layer and the full joint joint can make the square brick more durable and avoid falling off and cracking during use.
8. During the construction process, sprinkle the raft on the paving surface in a timely manner, and clean it with a broom to wipe off the cement or other sticky materials left on the brick surface to avoid too long surface contamination and difficult to clean.
9. After 12 hours of paving, the brick surface should be tapped for inspection. If you hear the sound of “emptyâ€, it means that there is an empty drum and should be re-paved.
10. After the brick paving is finished for 24 hours, you can walk and scrub. Mix the detergent with water and thoroughly clean the square tiles. The bright square will be in front of you.
11. It can't be constructed in the cold winter stage. When the temperature is lower than 5 °C, antifreeze should be added to the cement mortar. After the construction, the brick surface will be covered with straw curtain to keep the cement hardened.
12. After the construction of the square brick, it should be sprinkled with water to promote the solidification of the cement mortar and the square brick. Generally, the 15 day square brick can be used normally.
Carburetant
Using the carburetant can make the most of the scrap steel and reduce using the pig iron. The content of carbon is very high. Its color is black.When the carburant is used in casting, the consumption of scrap steel can be greatly increased, and the consumption of pig iron can be reduced or pig iron is not needed. At present, most of the carburant is suitable for electric furnace smelting, and a small part of the carburant with particularly fast absorption speed is used for cupola. Charging method of electric furnace smelting, should be the carburant with waste steel and other materials into the casting, small dosage can choose to add on the surface of molten iron. But to avoid mass feeding into molten iron, in order to prevent excessive oxidation and carbon effect is not obvious and casting carbon content is not enough. The addition amount of the carburizing agent is determined according to the proportion of other raw materials and the carbon content. Different types of cast iron, according to the need to choose different types of carburant. The characteristics of carburant itself choose pure carbonaceous graphitizing substances, reduce excessive impurities in pig iron, the selection of carburant can reduce casting production costs.
