MIRA® 108 is a high performance new generation mid-range water reducer based on comb polymer technology. It is a ready-to-use liquid admixture with superior dispersing capacity for the cement particles in the concrete mix. This capability exceeds that of normal water-reducing admixtures, resulting in lower dosages and better control. MIRA 108 is formulated to comply with the following specifications for chemical admixture for concrete: ASTM C 494, Type F and Type G.
MIRA 108 contains no added chloride. One litre weighs approximately 1.05kg ± 0.02kg.
MIRA 108 produces concrete with extreme workability characteristics for middle slump, Grade 35 - Grade 50 concrete. It also allows concrete to be produced with low water-cement ratios at middle slump. MIRA 108 is ideal for use in 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.
Addition rates of MIRA 108 can vary with type of application. Depending on the application, dosage rates can range from 600 to 1,800mL / 100kg of cementitious material. However, in most applications, 800 to 1,200mL / 100kg of cementitious material will be sufficient. For best results, MIRA 108 should be added with the mix water. At a given water-cement ratio, the slump required for placement can be controlled by varying the addition rate. Should job site conditions require using more than recommended addition rates, please consult your local GCP representative.
Please contact your local GCP representative for further information regarding the dispensing equipment for this product.
See MIRA 108 Material Safety Data Sheet or consult GCP Applied Technologies.
In concrete containing MIRA 108 the use of an air-entraining agent (such as DARAVAIR® or DAREX® AEA®) is recommended to provide suitable air void parameters for resistance against freeze-thaw attack. Due to synergistic effects between MIRA 108 and airentraining agents, the quantity of air-entraining admixture added to concrete containing MIRA 108 may be reduced. Please consult your local GCP representative for dosage guidance.
MIRA 108 is not compatible with Naphthalene-based or similar type of products.
Most water reducers or water-reducing retarders are compatible with MIRA 108 as long as they are added separately to the concrete.
Caution should be exercised when using MIRA 108 with a retarder, as excessive retardation can occur if the admixture dosages are too high. Pre-testing of the concrete should be performed to optimise dosages and addition times of these admixtures. The admixtures should not be in contact with each other before they enter the concrete.
MIRA 108 is available in bulk and in 205L drums. MIRA 108 contains no flammable ingredients.
In storage, and for proper dispensing, MIRA 108 should be maintained at temperatures above 0ºC. MIRA 108 should be stored under shelter and away from direct sunlight. Shelf life is six months from the date of delivery.
