Question

use of waste materials​

Answer 1

Answer:

Waste materials are a major environmental problem, which is a threat to the environment. It is important to reuse these materials and dispose of them. Waste can be used in the construction industry in two ways: by reusing (reuse components) and recycling (processing waste into raw materials used in the production of building materials). The paper presents my own research using substrates resulting from the processing of waste: foam glass and high-impact polystyrene and the possibility of their use as modifiers composition of basic construction materials. Glass foam is made from glass cutlet. It has many advantages, positive effect on the adsorption of sound and work ability. Due to the spherical shape and low density it is used as an ultra-light filler. The second addition is High Impact Polystyrene (High Impact Polystyrene - HIPS for short) which is a butane rubber modified polystyrene. With the change amount of the rubber mechanical and physical properties of the material are also changed, for example, by increasing the toughness of HIPS. The article presents a critical review of the literature on changes in the composition of traditional building materials on the example of cellular concrete, cement and products of sand - lime. The paper presents my own research and detailed analysis of them. The aim of the study was to determine the impact of additives on the parameters of the physical and mechanical properties and micro structure of the newly created materials compared to their traditional counterparts. The analysis has been subjected to the results of my own research: comprehensive strength, water absorption, bulk density and construction of structural material. The results are presented in the form of tables and graphs.

best out of waste ideas for socks

What wastes you need:

1 sock from the pair (preferably white or light colored)

1 Coloured sock

Sesame seeds

Rubber bands

Map pins

Scissors

Glue

Buttons

Cloth or ribbon

What to do out of these:

Cut the white sock in half.

Turn it inside out and fill it with sesame seeds.

Make a nice round base and secure the top with a rubber band.

Tie another rubber band about 3/4th of the way up to make the head of the snowman.

Glue the buttons on the belly of the snowman

Use the map pins to make its eyes and mouth.

Use the top portion of the coloured sock to make the snowman’s hat.

Lastly, use the cloth or ribbon to make the snowman’s muffler. Your sock snowman is ready!
