ARDEX FEATHER FINISH is an underlayment formulated from a blend of Portland cement and other hydraulic cements that provides a smooth, permanent finish for a variety of substrates prior to the installation of today’s demanding floor coverings, including sheet vinyl and VCT (vinyl composition tile).
Because of the infiltration, ground water supplies are recharged and pollutants are treated.Pervious concrete pavement is a pavement type that allows rainwater and other sources of water to percolate into the base layer below the concrete.Thus allowing the base material to absorb and control the flow rate of the water as it moves off site.
Brushed concrete is a type of finish, in contrast to the smooth finish that people may refer to as finished concrete.The smooth finish is standard, but brushed concrete provides certain advantages -- and also disadvantages -- that you don't have with a smooth finish.
Cement and concrete finishers are responsible to pour, smooth, and finish surfaces such as walkways, roads, curbs, walls, etc.They accomplish this by using an assortment of hand tools and power tools.Concrete finishers typically will spread, level, and smooth out concrete surfaces using hand tools such as a trowel, shovel, rake, etc.
Cement plaster is a homogenous mixture of Portland cement, fine aggregates, and water.Generally, OPC 43 and OPC 53-grade cement is mixed with sand (the fine aggregate) in different proportions; hence, this plaster is also called as the cement-sand plaster.PPC cement is preferred in place of OPC-grade cement for plastering.
Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened .
Concrete mix should be poured to the height that is desired.You can add more concrete within 24 hours of the first pour.However this will have a cold joint between the two.When using Sakrete Fast Setting Concrete Mix we recommend to pour the water into the hole first then add the concrete mix.Slope top of mix to allow water to drain away.
Concrete Surface Finishes Page 3 defined by the specifier in a particular regard.An example would be an F5 finish where blowhole frequency was not important; the finish could be defined as “F5X – blowholes to be in range 1 to 4”.

Exposed aggregate concrete is a common approach to improving the appearance and functionality of concrete surfaces like driveways, parking aprons, and floors.The cost to apply average exposed aggregate concrete depends upon surface area, the type and color of stones, special preparation needs, and the labor rate.
Feb 05, 2014 Concrete temperature, wind speed, relative humidity, and ambient temperature all affect the evaporation rate of water from the concrete surface.If the evaporation rate is too great or the bleed rate is too slow, the surface of the concrete will dry out, making it difficult to close.This loss of moisture at the surface is part of the paste .
Finishes, such as broom finished or scarified floors At standard coverage rates, the Ashford Formula cannot resolve dusting or erosion problems related to over-troweling, carbonation or poor surface water-to-cement ratio.
Higher rate is possible (up to 7 kg/m 2), but it is highly dependent on the site conditions, concrete formula, and the water content in the concrete.Higher application rates by hand are best performed using two stages.
Introduction of water to concrete mixture at batch plant to initial power floating.Dry-shake—dry mixture of hydraulic cement and fine aggregate (either mineral or metallic) that is distributed evenly over the surface of concrete flatwork and worked into the surface before time of final setting and then floated and troweled to desired finish.

Type of cement is no guarantee against other bad concreting practices To be durable, you have to get the basics right: the cement type is just an aid Water-cement ratio is key Top picture – w/c 0.69, Type V Bottom picture – w/c 0.
Typically, the water/cement ratio is the single most important determining criteria for the drying of concrete.For a concrete with a water/cement ratio of 0.70, the drying time to reach 90% RH is anywhere from 3 to 9 months, under suitable drying conditions.Concrete utilizing a water/cement ratio of 0.
Using the manufacturer’s recommendations, place the cement, sand, (aggregates if making concrete), and water into separate plastic buckets.For a standard mortar mix this normally on a ratio basis (usually around 3 or 4 parts building sand to 1 part cement) recommendations vary – but you don’t want the mixture to be too wet or too dry.
Water required = Weight of total dry material * 20% = (50+230) x 0.056 cum *(Keep this handy to derive initial water requirement in any cement mortar) Step-2: Calculate the volumeof wet plaster mixture.Cement = 50 kgs , Sand = 230 kgs and Water = 56 kgs.
