Concrete Floor Reflectance

Light reflectance value lrv is a measurement used to inform how much light a color reflects and how much it absorbs.

Concrete floor reflectance.

Using concrete mixtures with sufficient mixing water however the investigators reported. That is the finding from a portland cement association pca study which measured the solar reflectance index sri of 45 concrete mixes. Bright shiny and polished concrete floors look much better than a dull and dreary surface. Before the floor was dark typical of a steel troweled concrete floor and it was gouged by forklifts refracting instead of reflecting the light.

The scale ranges from 0 to 100 with 0 being. It can be important to maximise the light reflectance from an exposed surface for example to reduce the artificial lighting requirement. Concrete does a very good job of reflecting solar energy. Reflectance values for aged weathered or abraded concrete surfaces were affected by the reflectance of.

Reflectance values for 25 week old concrete produced with white and gray cement were 0 68 to 0 77 and 0 41 to 0 52 respectively. Measuring the reflectance of floors for big box retail stores it s not only the levelness and flatness of a floor that counts it s also the ability of a floor to reflect light that matters. They reflect heat from the sun and do not warm the air very much. This is the text promo text here.

An as struck smooth grey portland cement surface may have a reflectance of 40 cibse although this will reduce if the surface is mottled or discoloured.
