TASK 1:
Question: The diagram shows the process of making a storage warehouse for concrete canvas.
ANSWER:
The illustrations show how to build a storage structure using concrete canvas. Overall, the process has eight steps, starting with making the canvas, then forming the storage room, and ending with using the final product.
The first four steps prepare the storage structure. First, concrete canvas is made by stacking three different layers: the top layer absorbs water, the middle layer is dry concrete fiber, and the bottom layer is water-resistant plastic. After that, the packed concrete canvas is loaded onto a truck for delivery. At the site, the canvas is unwrapped and secured to the ground at one end with pegs, while the other end is tied to the truck with a rope. The truck then moves to stretch the canvas until it is 10 meters long.
The remaining steps create the storage area. An air pump is used to blow air underneath the concrete canvas, inflating the area until the ceiling reaches 2.5 meters. Next, a door is installed, and the top of the canvas is sprayed with water. After 20 to 24 hours, the canvas structure is fully hardened and ready for use.
