The properties of silicate products modified by LDPE granules

The following article presents the results obtained through the modification of sand-lime matter. The modifying filler is a low-density polyethylene granules (hereinafter referred to as LDPE), formed as a result of the recycling process. The main purpose of the research was to receive a lightweight, recyclable product with physical and mechanical properties similar to above mentioned traditional sand-lime products. The filler has given the desired effect, however the compressive strength of newly created elements has significantly decreased. It is therefore concluded that from the building operation point of view, modified products that contain less than 9% of LDPE filter are relevant. The paper describes the examination methodology and the results in the form of tables and graphs.
