Pozzolanic materials are characterized by the presence of a high amount of amorphous SiO2 and can react with portlandite (lime), which is a by-product of the cement hydration process.
Similar pozzolanic materials, such as fly ash, blast furnace slag, silica fume, etc. have been successfully utilized in cement-based materials for many years.
Therefore, to properly utilize waste glass in cement-based materials a detailed analysis of the material itself is required.
Used Materials Cement.

Introduction
The core of the researches devoted at investigating the machinability of metallic alloys by means of both numerical and experimental approaches are concentrated on the as defined Difficult-To-Cut (DTC) materials because of the higher industrial demand of overcoming the problems connected with machining of these alloys.

Materials and methods
The experimental program was carried out at the Civil Engineering laboratory of University of Minho and involved the characterisation of 8 low cost meshes made of different materials and 9 mortars with different compositions.
The particle size distribution of the earth based mortars and constituent materials is given in Fig. 2.
Hydraulic lime was chosen, since this binder is expectedly more compatible with earthen materials.

Introduction
Polymeric materials based on polylactide acquire their significant importance in a variety of human activities.
Such materials are biocompatible, do not cause any environmental pollution as in the process of biopolymer production, the CO2 emission into the atmosphere is 2-3 times lower [1, 2].
Large raw materials, material and energy resources are required to implement these steps.
At the same time, the recycling share of spent polymeric materials and products based on polylactide is very small.

Congestion points because of wrong-side movements
c) Potholes: Potholes are also the main source of congestion in developing countries when pavement is not properly maintained or use of unsatisfactory material during construction, causing the road to deteriorate, ultimately forming the potholes
