Flatwork can be challenging for concrete contractors. For high-end residential and commercial construction, concrete producers need a mix that can be easy to place and finish. For these applications, the use of MIRA® admixtures is the key.
MIRA® 2116 is a high range water reducer, commonly referred to as a superplasticiser. It is an aqueous solution of a modified naphthalene sulfonate.
Mira 2116 produces concrete with extremely workable characteristics referred to as high slump, flowing concrete. Mira 2116 also allows concrete to be produced with very low water-cement ratios at low or normal slumps. Mira 2116 is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water-cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation. Mira 2116 will also fluidise concrete making it ideal for tremie concreting or other applications where high slumps are desired.
MIRA® 388 is a high performance, new generation mid-range water reducer based on comb polymer technology.
High-end residential and commercial buildings require high quality flatwork concrete to go along with them. Builders want to make sure that this concrete will be suitable for fast construction methods, so they turn to MIRA® products. The MIRA® family of mid-range water reducers bridge the performance between normal and high-range water reduction. It offers excellent linear dosage water reduction capability, near neutral set times over a wide range of dosages and excellent placement and finishing properties.
Some MIRA® products are formulated to provide excellent water reduction, compressive strength and set time when used in mix designs containing high pozzolan contents. These performance improvements are due to a superior dispersion and strength enhancing capability, plus superior quality control that ensures consistent performance.
Other MIRA® products are formulated to provide excellent overall performance as low-range to mid-range linear-dose water reducers. These can be used in a variety of applications, including ready mix, paving mixes and precast products. They produce higher early and ultimate compressive strengths, with neutral set times, allowing higher levels of water reduction less permeable and more durable concrete.
