Generally, the mix of aggregate to cement is 2.5 to 1 by volume. [1] Granolithic screed or paving can be problematic. Because it is made with a high cement content and requires a great deal of water to mix, it may crack while drying. [3] It can also come loose from the material below (especially if the lower material is not properly prepared). [3]
Design mix ratios are decided by an engineer after analyzing the properties of the specific ingredients being used. Instead of using a 'nominal mix' of 1 part cement, 2 parts sand, and 4 parts aggregate, a civil engineer will custom-design a concrete mix to exactly meet the requirements of the site and conditions, setting material ratios and ...
It is created by using small lightweight EPS balls (sometimes called Styrofoam) as an aggregate instead of the crushed stone that is used in regular concrete. [3] It is not as strong as stone-based concrete mixes, but has other advantages such as increased thermal and sound insulation properties, easy shaping and ability to be formed by hand ...
After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold that may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish. After sufficient hardening, the surface is cleaned and generally sealed to provide protection.
Polished concrete may be considered a form of sustainable design flooring, if less material is used than in comparable types of flooring. [citation needed] Polished concrete floors have the following advantages: low-maintenance [7] – polished concrete is easily maintained with the use of clean water or a neutral pH cleaner. The application of ...
Wet-mix shotcrete involves pumping of a previously prepared concrete, typically ready-mixed concrete, to the nozzle. Compressed air is introduced at the nozzle to impel the mixture onto the receiving surface. The wet-process procedure generally produces less rebound, waste (when material falls to the floor), and dust compared to the dry-mix ...
The finish layer contains the coloration used to imitate stone and is textured using waxed paper and an aluminum roller. [3] Mica could also be sprayed on the surface to give the Formstone a sparkly, clean look. Mortar joints are then scored into the top layer to mimic natural stone construction. [6] [3]
