Cement is the most important component of concrete. 1_______. Concrete may be considered an artificial conglomerate of “crushed stone, gravel or similar inert material with a mortar”. A mortar is a mixture of sand, screenings or similar inert particles with cement and water. 2_______. The most accurate method of measuring proportions is to weigh the required quantities of each material. This may be done whether the proportions are based upon volumes or weights. 3_______. It is also widely used in large building constructions. 4_______.

The Best Building Materials
1. Building materials are very important in the construction. But it is more important for any designer to select and adapt such building materials of construction that will give the most effective result by the most economical means. In this choice of materials for any work of constructions many factors must be considered by the civil engineer. These factors include availability, cost, physical properties of materials and others.
2. Practically, all buildings materials have their advantages and disadvantages. That's why some materials are used most widely in building construction for the purpose of binding together masonry units. Among them are lime, gypsum and cement.
3. Last material forms very important elements in all masonry structures, such as stone, a brick. Since the time of its introduction a gradual improvement of Portland cement quality has led to the elaboration of rapid hardening Portland cement, or «high early strength». Later developments include low heat and sulphateresisting cements. The scope for such purpose-made cements has led to the development of an increasing variety such as high alumina cement, blast-furnace slag. They may be also white and coloured cements.

Windows were formerly made on the job site by highly skilled carpenters, but are now produced almost exclusively in factories. 1_______.Windows need to be made to a very high standard of precision if they are to operate easily and maintain a high degree of weather tightness over a period of many years. In cold climates especially, a loosely fitted window with single glass and a frame that is highly conductive of heat will significantly increase heating consumption for a building, cause noticeable discomfort to the people in the building, and create large quantities of condensate to stain and decay finish materials in and around the window.
2_______. Single-hung and double-hung windows have one or two moving sashes, which are the frames in which the glass is mounted. 3_______. A sliding window is essentially a single-hung window. 4_______.

The plant where high-density polyethylene pipe is being manufactured needed repairs to its pipe storage area. The repairs became necessary because the stone layer did not shed water and it caused cracks. The cracking of the storage pavement area made it necessary to stabilize the site.
So it became necessary for engineers to look for a way that would be economical and would not require shutting down the operating area of the plant. After testing a number of alternatives, it was decided to use polypropylene fibres for the purpose. It was found out that when being mixed with soil the fibres produce the necessary stability. The way the engineers proposed turned out to be economical and quite successful.

The fibre reinforced polymer bridge deck is a newly-invented arrangement. It is made up of composite materials. They are extremely useful since, because of their composition, they have a wide range of application. Compared with other conventional materials they can solve a much greater number of problems.
One of the advantages of the bridge deck is that it is highly resistant to corrosion and fatigue. The material it is made up of is very easy to transport; it also allows rapid installation using lighter equipment and much less manpower. Holes are easily cut in the deck. They can be closed out to accommodate the same drainage scuppers that are used on conventional decks.

F. Hennebique was born in France, in the family of a farmer. Already in his childhood he became fond of natural sciences and spent his free time on reading books on natural sciences. At the age of 18 he became an apprentice of a builder and at the same time he continued his studies of theoretical technology. At the age of 25 years Hennebique specialized in restoring churches. He travelled all over the country visiting cathedrals and examining their architecture and construction.
As years passed by, he grew interested in railway works, including bridges and viaducts. In 1844 he designed a house for a client and, to prevent damage by fire, combined good-quality steel with concrete in compression. In this way he realized a new idea to put steel rods in the bottom of the slab in order to prevent any damage by fire. That building with its fire resistance guarantee was completed in 1880 and stood until destroyed during the First World War.
From that time on, F. Hennebique concentrated on the development and production of reinforced concrete constructions. One of his reinforced concrete buildings of that time, a single-storey structure in Paris, had a concrete and glass roof.
