What Can I Do For You?
coloured concrete colori coloured concrete can be finished using a variety of conventional methods: • ™expose exposed aggregate; • boralstone™ polished and honed concrete; • broom finish; • machine trowel finish; • off form or precast concrete; • sand blast finishesand; • textured
concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and portland cement. cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. this combination, or concrete mix, will be poured and harden into

the broom finish of the concrete is rough textured finished obtained by dragging a broom on the trowelled surface of the concrete while the concrete is still fresh. fig 2: broom finished concrete. dragging of broom on the fresh concrete surfaces creates small ridges that provide for traction control and slip-resistant.

the concrete will be created using a shading network and the grout will be created from a ps file. basically, i want the grout to remain the same for every square and the concrete mix to be random (more realistic). in a sense, you can see it like a picture frame where the picture changes and the frame remains the same.
acid etching concrete creates only a minimal profile. concrete surface profile, or csp, as defined by the international concrete repair institute (icri), is a standardized measure for the ‘roughness’ of a given concrete surface.this can range from csp-1 (smoothest) to csp-9 (roughest). the thicker the coating system, the higher the required csp number.
these concrete textures will perfectly fit any kind of project. each concrete texture is available for downloading. download cg textures with .jpg, .png, .psd, .tga, .tif, .hdr and .i3d formats. you will undoubtedly find something useful in the categories buildings textures and decals textures.

cement. the environmental impact of frost-resistant concrete is between 24-41 % higher than that of ordinary concrete due to its higher content of cement. superplasticizers contribute with approximately 0.4-10.4 % of the total environmental impact of concrete, the least to
weathering of concrete. weathering is the effect of pollution and natural forces, such as frost, rain and sunlight, on a structure. with concrete, the main weathering problem is unexpected variations in the visual appearance of the structure. dust in the atmosphere will be deposited on the facade.
rough-textured, angular, and elongated particles require more water to produce workable concrete than smooth, rounded compact aggregate. consequently, the cement content must also be increased to maintain the water-cement ratio. generally, flat and elongated particles are avoided or are limited to about 15 percent by weight of the total aggregate.
the starting pattern imprinted concrete cost per m 2 might be lower than cbp, but it can also work out more expensive too. again this depends on several factors, but you’ll be looking at between £25 and £130 per square metre. example: for a 50m 2 driveway, your estimated cost could range from £1,250 to

cemex does not “simply manufacture concrete”, but develops solutions based on the thorough knowledge and application of concrete technology. leveraging years of experience, a worldwide pool of knowledge, and state-of-the-art expertise about the different concrete constituents and their interaction, cemex offers its customers “concrete by design”—tailor-designed concrete.
components of concrete are cement, sand, aggregates and water. mixture of portland cement and water is called as paste. so, concrete can be called as a mixture of paste, sand and aggregates. sometimes rocks are used instead of aggregates. the cement paste coats the surface of the fine and coarse aggregates when mixed thoroughly and binds them.
when the environmental impacts of concrete are considered, the economic impacts are also involved within. because the concrete is produced locally, there are very low transportation costs. transporting concrete to the landfill can cost as much as $0.25 per ton per mile.
step 2: another experiment. this experiment uses a regular mix of sand, cement and water, and the porosity between the gravel-size particles is saturated with the mix. the resulting concrete is stronger than the earlier experiment, but also heavier. ask question.
