The physical properties of aggregate play an important role in elastic and shrinkage properties of concrete and mortar.
It is well known that properties of aggregate strongly affect the mechanical and durability properties of concrete.
The shape and texture of aggregates affects the fresh and hardened properties of concrete.
The minerals present in the aggregate affect the strength and durability properties of concrete.
The shrinkage behaviour mainly depends upon the following factors: modulus of elasticity, particle shape, grading, maximum size of aggregate and clay minerals.

Experimental Investigation of the Flammable Properties and Factors of Wooden Products Exposed to the Fire Impact DUBININ Dmytro1,a*, LISNIAK Andrei1,b, SHEVCHENKO Serhii1,c, GAPONENKO Yuri1,d 1National University of Civil Defence of Ukraine, 94, Chernishevska str., Kharkiv, 61023, Ukraine adybinin@nuczu.edu.ua, bptarr@nuczu.edu.ua, cshevchenkosn@nuczu.edu.ua, dgaponenkoyurii66@gmail.com Keywords: thermal decomposition, pyrolysis zone, char layer, depth of char, OSB and WPB.
Consideration was given to the issue of the integrated evaluation of the flammable properties and factors of wooden products (Oriented Strand Boards, OSB and Wood Particle Boards, WPB) as basic flammable construction materials exposed to the action of fire.
It should be noted that the composition and properties of pyrolysis products are primarily affected by the type of wood and its quality, the size of the raw material particles and the initial moisture content in the raw material, the rate of heating, the time of exposure of the raw material to any given temperature, final heating temperature, the circulation rate of the gas flow through the wooden layer and other factors.
Summary Experimental investigations were carried out to determine the flammable properties and factors of wooden products (OSB and WPB) exposed to the fire impact.

The properties of cement have a direct relationship with the quality of engineering structure.
The test of strength of cement is affected by many factors, such as the ratio of cement mortar, operating parameters, curing conditions, test mould and cement compression jig status [5,6].
Among the operating parameters, the factors obviously affecting cement strengths are the smooth operation, ready to face as a force, a release form and the way putting on to concrete，the factors slightly affecting cement strengths are the pilot machine to a balanced perspective, the location and the pressure test machine speed [7].
In this paper, factors affecting cement strength test are divided into two categories, which are personnel operation and apparatus.
A series of experiments were conducted for exploring the influence factors.

The physical and mechanical properties of the materials such as the design, form of production, microstructure, and surface conditions of the material determine the severity of the damage [2].
However, these factors are not the only ones that play a role in this process [12-13].
It is, thus, important to study the fatigue behaviour for the estimation of the changes in the cumulative damage and the properties of the material.
The data for the fatigue properties are commonly collected from experimental tests as well as analytical or numerical models [20].
Furthermore, there is a decrease in fatigue life as the rate of oxidation increases, affecting the mechanical properties.

Introduction The performance of a power plant can be expressed through some common performance factors as heat rate (energy efficiency), thermal efficiency, capacity factor, load factor, economic efficiency, operational efficiency etc.
