The MAI®2MIX-MAIA-MOBIL is part of the latest generation of robust and dismountable continuous single shaft mixers, producing perfect mixing quality every time. It has a maximum mixing capacity of 40 to 80 l/min and a maximum grain size of 6 mm (or 8mm although increased wear is possible at this level).
Common materials used to construct poles include steel, aluminum and fiberglass, with steel being the most common due to its strength and affordability. In some cases concrete, cast iron and wood may also be used. While the most common pole shapes are
Figure 1. In Figure 2 are shown four common general defects: (a) placing concrete by free fall without directing the stream away from reinforcing steel or the sides of the excavation, (b) excavating a borehole for a drilled shaft near a shaft that has just been concreted, (c) placing concrete through water that
Concrete homes are common in areas where there is a lot of moisture. Unlike wood, concrete doesn't attract mildew or rot when it's wet for a long period of time. It's also resistant to termites and other critters that damage homes that are constructed with a lot of

Types of deep foundation and its uses in construction is discussed. Deep foundation carry loads from structure through weak soils to rocks at a large depth. Deep foundation is required to carry loads from a structure through weak compressible soils or fills on to stronger and less compressible soils or rocks at depth, or for functional reasons.
CGC Shaft Wall Systems are non-load-bearing gypsum wall partition assemblies constructed from outside the shaft at each floor. Shafts are enclosed early in construction, and the walls are finished later, along with interior partitions. Installation is quick and easy, using components and application procedures familiar to drywall contractors.
Jul 21, 2016 · Why and When to Use Concrete Piles? Different types of concrete piles are used for different applications. Cast-in-place concrete piles, or driven shafts are two great examples of how the can be produced (made) and installed. When choosing a pile type, one should generally consider the following conditions: 1- Poor quality of upper soil layers
Shaft keys are important machine components designed to transmit torque and rotative force. There are several types of shaft keys, each with their own particular role and application. Here we look at the different types: Shaft Keys, Shaft Key Design, Rectangular keys, Square keys, Woodruff keys, GIB keys, Taper Keys.
The Column formwork facilitates fixing of working platforms for access, checking of reinforcement, concreting etc., The formwork panel along with the working platform and alignment systems can be lifted as a single unit using a crane thus the labour involved in each operation of erection and deshuttering is reduced to a minimum.

Concrete frame structures are a very common - or perhaps the most common- type of modern building internationally. As the name suggests, this type of building consists of a frame or skeleton of concrete. Horizontal members of this frame are called beams, and vertical members are called columns.
Drilled Shafts 1 Mullins Drilled Shafts Introduction Drilled shafts are deep, cylindrical, cast-in-place concrete foundations poured in and formed by a bored (i.e. “drilled”) excavation. They can range from 2 to 30 feet in diameter and can be over 300 feet in length. The term drilled shaft is synonymous with cast-in-situ piles , bored piles ...
2020/1/2 · A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water ...
Apr 02, 2020 · In most shaft mines, most of these sections are used for lifting purposes. The service cage itself usually contains a large elevator, which is used to transport mining personnel up and down the shaft to different levels. The sections are usually rectangular in shape and are lined with either timber or concrete.
Create a new account Are you an ASCE Member? We recommend that you register using the same email address you use to maintain your ASCE Member account. A 3 × 3 bored pile group consisting of nine cast-in-drilled-hole reinforced concrete shafts and a comparable single-shaft were subjected to reversed cyclic, lateral head loading to investigate group interaction effects across a wide range of ...
In the single-shaft configuration, steam from each HRSG was fed to a separate steam turbine with no interconnection between the two steam cycles. The exhaust system for the single-shaft configuration did not include a by-pass stack, as only one of the single-shaft trains will be in operation and the second will be in an outage condition.

The principle disadvantage is the relatively high cost of the cement required to make the concrete. Concrete blocks: Concrete blocks may be used to construct attractive and durable foundation walls. The forms required for poured-concrete walls are unnecessary and, because of their large size, concrete blocks will lay up faster than bricks.
Before start on with types of foundation repair, any one may have the doubt, how to identify the foundation problems? For them, following are some of the reasons which may help to find the issues in foundation. Bumpy or descending floor which cause the floor to separate from its floor, cracks in the bricks or blocks of a wall, cracks in the ceiling decorations/ mouldings, swelling exposure of ...
DESIGN METHODS FOR SHAFT CONCRETE LINING AND SHAFT STATIONS In many countries there are certain regulations that standardize the mine design. In Poland, the Regulation of Ministry for Economy is applied (2002), which defines the requirements that the shaft anchored lining has to fulfil in the specified conditions.
Masonry provides a significant improvement in fire safety for building walls. Concrete masonry is typically used for firewall construction. The fire resistive characteristics are based on the thickness of the masonry. Acoustics.

Types Of Footings Used In Building Construction: Footing is one of the most important parts of a structure which transfers loads of a structure to the underlying soil. The selection of suitable type of footing generally depends on the following factors:
CHAPTER 2 QUANTITY TAKE-OFF The quantity “takeoff” is an important part of the cost estimate. It must be as accurate as possible and should be based on all available engineering and design data. Use of appropriate automation tools is highly recommended. Accuracy and completeness are critical factors in all cost estimates.
minimum acceptable wait. Because the concrete strength and quality generally increases as the concrete cures, longer wait times are usually desirable, particularly if minimum pulse wave speeds are specified or to reduce result variability between drilled shafts or even as a function of depth in a single drilled shaft.
