170 5.2 SPECIAL APPLICATION PRODUCTS & IMPROVING ADDITIVES 5.2.2 Admixtures for concrete - mortars & coatings DISCOUNT CATEGORY: Α NOTE: Please contact us for specific delivery times and schedules on all items marked ‘SPECIAL ORDER’. DUROSTICK D-84 Concrete set retarder & plasticizer (AS-308, ASTM C-494 type B&D, EN 934-2: T10) Its addition to wet concrete slows down the curing process, plasticizes it and at the same time facilitates its flow. Its use creates the conditions for optimal hydration of the concrete, increasing its final strength. Essential for transporting concrete, especially during the summer months. Also, the addition of a small amount in plastering machines slows down the cure of the plaster in the transfer hoses and improves its pumpability. Color: brown. Consumption: From 0.2-0.3kg per 100kg of cement. Indicative concrete mixing ratios: C25/30: (350kg cement/m3): 0.70 -1.05kg D-84/m3 of concrete. 20kg (147207) (SPECIAL ORDER) - 180kg (147184) (SPECIAL ORDER) - 1000kg (147108) (SPECIAL ORDER) - DUROSTICK D-44 Super plasticizer for concrete (per EN 934-2: T11.1 and Τ11.2) Increases the workability of concrete without the necessity of adding extra water. Increases concrete pumpability, thus reducing the need for vibration, providing perfectly poured concrete surfaces. Reduces the water/cement ratio by 10-15%, increasing all mechanical strengths. Color: brown. Consumption: • As type D plasticizer: 0.3-0.6kg per 100kg of cement. • As type G super plasticizer: 0.6-0.8kg per 100kg of cement. • As type A plasticizer: 0.3-0.4kg per 100kg of cement. 20kg (040201) - 180kg (040188) (SPECIAL ORDER) - DUROSTICK ANTIFREEZE POWDER Antifreeze admixture for concrete and mortars Cement accelerator in powder form. When added to ready-mixed or traditional cement mortars (with normal cure times), it accelerates the development of their mechanical strength at low temperatures. Its addition accelerates the activation of the cement contained in mortars and helps to hydrate it quickly, reducing its setting and curing times and preventing frost damage during maturation as well as application failures due to temperature variations. Color: white. Consumption: • It is recommended that a 500gr bag be added directly to the mixing water for every 25kg bag of cement mortar, such as: tile adhesives, thermal insulation boards, base coat plasters, repair mortars, etc. • It is recommended to add 2kg (4 bags) for every 50kg cement in traditional mortars to accelerate cure times. 500gr (858028) 12 PRODUCT DESCRIPTION PACKAGING (Code) PCS/ BOX €/kg €/PACK. DUROSTICK D-34 HYDROSTOP Concrete plasticizer & water reducing admixture (AS-308, ASTM C-494 type Α, per EN 934-2: T2 & T9) Its addition to wet concrete improves its watertightness and increases its mass density as well as its plasticity. It also enhances all its mechanical strengths, reducing by 10% the water/cement ratio. Necessary for creating watertight foundations on soil with increased moisture levels. Color: brown. Consumption: 0.3-0.5kg per 100kg of cement. Indicative concrete mixing ratios: C16/20: (270kg cement/m³): 0.80-1.35kg D-34/m³ of concrete. C25/30: (350kg cement/m³): 1.00 -1.75kg D-34/m³ of concrete. 1kg (911013) 15 5kg (911051) - 20kg (911204) - 180kg (911181) (SPECIAL ORDER) -
