You have probably seen people cover freshly done concrete work with plastic while it is curing. Why do they bother with this? So that dirt does not blow onto the concrete during the curing period? While it is true that covering the curing concrete with plastic will keep it cleaner, there is a more essential purpose behind this practice ...
Concrete dams are built in four basic shapes. The concrete gravity dam has weight as its strength. A cross section of this dam looks like a triangle, and the wide base is about three-fourths of the height of the dam. Water in the reservoir upstream of the dam pushes horizontally against the dam, and ...
Thin plastic like this is often called a vapor retarder—meaning it slows the vapor down but doesn't stop it. A much better approach is a true vapor barrier, with characteristics that conform to the requirements of ASTM E-1745, "Standard Specification for Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs."
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
"Cement stave silos were promoted as being permanent, durable, and resistant to fire. They were cheaper than silos of brick and clay tile, and no special masonry skills were needed. They were more durable than concrete block silos and did not need forms used in monolithic concrete," according to the Minnesota Historic Farms Study.

What They Do: Masonry workers use bricks, concrete blocks, concrete, and natural and manmade stones to build masonry structures.. Work Environment: The work is physically demanding because masons lift heavy materials and often must stand, kneel, and bend for long periods.Poor weather conditions may reduce work activity because masons usually work outdoors.
What this introductory guide seeks to do is describe the apparatus in layman's terms and also outline how they work and what they were intended for originally and the purposes for which they are used today. We begin with a brief definition of what a windmill is.
Tower cranes are a common fixture at any major construction site. They're pretty hard to miss -- they often rise hundreds of feet into the air, and can reach out just as far. The construction crew uses the tower crane to lift steel, concrete, large tools like acetylene torches and generators, and a ...

The use of concrete in construction grew rapidly from 1850 onward, and was soon the dominant use for cements. Thus Portland cement began its predominant role. Isaac Charles Johnson further refined the production of meso-Portland cement (middle stage of development) and claimed he was the real father of Portland cement.

How They Work. Scarifiers, also called surface planers or milling machines, remove concrete faster and more aggressively than grinders. That's because they use the pummeling action of multi-tipped cutting wheels, or flails, that rotate at high speeds to chip away at the concrete surface.
Other uses Include, skid resistant asphalt aggregate, rail ballast asphaltic concrete aggregate, soil conditioner, hard stand areas and unconfined construction fill.
