Superplasticizers (High Range Water reducer) ASTM C494 Type F and Type G, High Range Water Reducer (HRWR) and retarding admixtures are used to reduce the amount of water by 12% to 30% while maintaining a certain level of consistency and workability (typically from 75 mm to 200 mm) and to increase workability for reduction in w/cm ratio. The combined water reducing and superplasticizing action in all three cases provide the following benefits: Mid Range Water Reducing Applications: Mid range application will be beneficial especially in ready mix applications. Especially beneficial in ready-mix applications. For these applications, the use of MIRA® admixtures is the key. phone +1 (201) 933-8800 Increased concrete durability and uniformity. By reducing water SikaPlast®-500 improves durability and increases compressive strength. Mid-range water-reducing admixtures were developed to increase the slump beyond the range available with regular water reducers without the excessive retardation that had been known to occur. Glenium). www.tylerley.com Greater concrete density reduces permeability and increases durability. Mid-range water-reducing admixtures promote superior workability and finishing of concrete, and improve concrete performance with excellent early strength and rheology. It can be used in a mortar to improve the workability, fluidity, and strength of concrete. We can reduce greenhouse gas emissions, protect our infrastructure and our ecosystems,” said Spivy-Weber. Sodium lignosulphonate has three functions. Mid Range Water Reducing Applications: At a lower dosage, Sikament®-686 can be used as a cost effective mid range water reducing admixture or simply as a water reducing admixture for production of conventional slump concrete. Mid-Range Water-Reducing Applications: Medium dosage, cost-effective water reducer. Pozzolith), mid-range (e.g. These constraints on water supply led water agencies to implement a range of water conservation and watering restrictions programs, mostly targeted at outdoor use. Ideal for lean, harsh, ready-mix concrete. Mid Range Water Reducing Applications: Mid range application will be beneficial especially in ready mix applications. Lyndhurst New Jersey 07071 Mid-range water reducers provide more consistent setting times than standard water reducers. This action builds on a . Sikament® AFM will improve workability and finishability. Increased compressive and flexural strengths. It is supplied as a brown colored, low viscosity liquid. Improves pumpability and reduces stickiness in concrete. There are three types of water reducing admixtures for concrete: High-range, mid-range and normal: High-range water reducers provide outstanding engineering performance and or concrete workability. Increased slump improves workability and reduces labor costs. MIRA® 151 is a mid-range water reducer specifically formulated to produce concretes with enhanced finishing characteristics and controlled set time. Please login with your username and password. Description MasterPolyheed 1025 admixture is a patent pending ready-to-use mid-range water-reducing admixture. Mid range water reducing admixtures consist of a mix of chemicals aiming to reduce the water to cement ratio in concrete. Low Range Water Reducing Applications: SikaPlast®-500 can be used as an economical low dosage admixture for conventional slump concrete, where water reduction up to 5% is required. It is manufactured under rigid control, which provide uniform predictable performance. The dispersing action of Sikament® AFM maximizes cement hydration efficiency and improves concreteâs early and long term compressive strengths.
