Exposed concrete floors. Exposed concrete floors are durable, hard wearing and useful for all sorts of applications from warehouses to art galleries and garages to domestic living rooms. They are particularly useful for heavy loads or traffic or, when combined with underfloor heating, for continuous and efficient space heating. As a finish they can appear utilitarian or luxurious depending very much upon the chosen materials and installation techniques. Technically, the upper face of a
concrete is incredibly hard and strong — no wonder it's used for streets and driveways! As a flooring material, it has all the strength and durability of a highway. You can't scratch or dent a concrete floor. It also can make a fashion statement. Added dyes and etching techniques can turn gray, boring concrete into your home's star attraction. Cost ranges from downright cheap ($2 per square foot) to relatively pricey ($30 per square foot, depending on finishes). Obviously, concrete is
Where heavy traffic or other special conditions are expected, a special finish layer or hardening treatment is desirable. Heavy duty topping may be placed on the base slab while it is still in a plastic condition or after the slab has hardened. Both methods give satisfactory results provided preparation of the base has been done properly. The continuously placed two course floor is considered to be superior to unbonded or slush coat bonded types because it allows for better control of

In 1875, the Public Health Act was introduced. It required urban authorities to make byelaws for new streets, to ensure structural stability of houses and prevent fires, and to provide for the drainage of buildings and the provision of air space around buildings. Three years later the Building Act of 1878 provided more
I am aware that there are several ways to get thin, long-wearing toppings, but I do not know how to go about evaluating these other techniques. I would appreciate any comments you might have about this problem. You are producing a highly satisfactory floor, but the delay in finishing makes it a rather expensive floor. The 4-hour waiting period seems excessively long. It could be shortened by using a rich mix (6 1/2 to 7 bags cement per cubic yard of concrete) of not more than a 2-inch
Retaining moisture in concrete is a good thing if the ultimate goal is a good curing condition, but what if you must install finished flooring materials requiring low concrete relative humidity (RH)? In this case, you'll need your slab to dry out as soon as possible. But drying can be a slow process and contractors often find themselves in conflict with construction schedules. Under these schedule pressures, finished floor surfaces are sometimes installed when the RH of
Reinforced concrete floor decks have become increasingly popular in homes over the last decade, and many of the floor systems used are adapted from commercial construction. However, some newer systems have been developed with lighter residential construction in mind. This has decreased costs and also contributed to concrete floors' popularity.
The concrete flooring can be constructed either (i) Monolithically i.e. base layer is laid and then immediately a concrete topping is provided. (ii) Non Monolithically i.e. the topping is laid after the base has set. Below is the cross-section of a concrete floor Where 1) 4 cm concrete topping 2) 10 cm lime or lean.
Cement concrete flooring is commonly used both in residential as well as public buildings.The method of laying cement concrete flooring on ground floor of a building can be broadly divided in the following steps.
Chartered surveyor Ian Rock explains the options for the ground and first floor structure for new homes and extensions including timber and concrete types. The methods used to construct new floors have come on in leaps and bounds in the last decade. Chartered surveyor Ian Rock explains the options for ground and first floor structures for Today, nearly all new houses employ beam and block construction for their ground floors. Although the cost of materials is
How to Place and Finish a concrete Floor. Whether building a home or an aircraft hangar, placing the slab changes the direction of your construction efforts. Before the slab is finished, the work crew is installing underground utilities,

Avoid common mistakes in concrete floor slab construction. Quality floor construction includes good subgrade compaction, even thickness slabs, low-slump concrete, straight bulkhead lines, and control cuts spaced 24 to 30 times the slab thickness. Common mistakes in concrete floor slab construction can Proper curing conditions are critical, and the curing method must be put in place as soon as the finished surface can resist damage. The concrete must not be
With the recent focus on sustainability and organic designs, chemically stained concrete flooring has achieved huge popularity. Acid staining produces a unique surface that's attractive, cost effective, and easily maintained. Although an increasing number of projects specify acid staining, many of these floors are being improperly installed. This is usually because the general contractor (GC) accepts the low bid and awards the contract to someone unqualified to do the

To prevent dampness rising from the Sand and Cement screed. Ground level. Timber floors. Suspended timber floor joists are supported by the walls which transfer the load from the floor, through the wall to the foundations. The traditional method of providing a flooring surface on top
concrete slab floors come in many forms and can be used to provide great thermal comfort and lifestyle advantages. Slabs can be on-ground, suspended, or a mix of both. They can be insulated, both underneath and on the edges. Conventional concrete has high embodied energy. It has been the most common material used in slabs but several new materials are available with dramatically reduced ecological impact. Different types Some types of concrete slabs may be more suitable
Structurally reinforced concrete construction becomes very efficient when bay sizes between columns don't exceed 20x30 feet. This creates an ideal situation for contractors to use flat-plate floor construction methods (the bottom of a floor slab is flat). Flat-plate floors reduce forming time and increase productivity. Owners also can benefit from this form of construction because it's sometimes possible to get an extra floor without increasing the height of a building.
The Euclid Chemical Company originally developed this floor design guide in order to integrate current design standards with proper construction practices and the selection of suitable materials. This updated edition reflects the current standards on floor slab construction that are found in ACI 302.1R-04, Guide for concrete. Floor and Slab construction. References to this document are made throughout this guide if the reader wishes to consult the appropriate section of ACI 302 for
Forms and shoring should be designed to allow safe, easy removal, while protecting the structure from excessive deflection at early ages. Evaluating concrete mix designs, delivery systems, and finishing techniques provides an opportunity to achieve the quality standards. Each decision will impact the flatness and levelness of the finished floor. concrete mixes must develop adequate strength while providing good consolidation, consistent set time, and workability.
concrete.TV visited one of the biggest jointless concrete flooring facilities in Silverstone to showcase the techniques and products used by concrete Laser flooring to tackle this mammoth job. The facility is 40 000 square meters and the role of concrete Laser flooring was to place the jointless floor to 190mm for Capital Properties. CLF has been around for 14 years and offers a turnkey flooring solutions through the use of sophisticated equipment and products.
There are two types of concrete floors used in industrial plants: monolithic and granolithic. Monolithic slabs make good structural concrete but the surface does not stand up well under severe wear. By contrast is a granolithic floor. A special "absorption process" granolithic floor topping has a high denstity, although it consists of essentially the same materials as found in convential concrete floors. These floors get their exceedingly high wear resistance from the method used to lay them.
nonreinforced concrete slabs. This guide describes how to produce high quality concrete slabs on ground and suspended floors for various classes of service. It emphasizes such aspects of construction as site preparation, concreting materials, concrete mixture proportions, concreting workmanship, joint construction, load transfer across joints, form stripping procedures, and curing. Finishing methods, flatness/levelness requirements, and measurements are outlined. A thorough
concrete Floors. In concrete screeded floors, the screed acts to diffuse the heat across the surface, providing an even temperature at floor level. Depending on the type of building, construction or standards, there are a number of methods for laying underfloor heating pipes in concrete floor structures. The most popular method of installation is as follows: A concrete slab (or suspended beam and block construction) is laid over a damp proof membrane. A 20mm thick piece of insulation is
