method of use:
1. The amount of the blend is in the range of 0.5-1.2%. Select the appropriate mixing dose according to the project object and the materials used in the construction process.
2. It is recommended to use FDN powder in the solution. It can be used in a dry state, but must be mixed with concrete should be fully stirred.
3. If the stagnant water mixing method or post mixing method is used, the water reduction dispersion effect is better.
4. This product can be formulated with other kinds of concrete admixtures. It can be mixed with fly ash, ground slag and other admixtures for "double doping", but the amount of admixtures should be calculated according to the total amount of cementitious materials.
5. When the product is used for the first time or the cement type is changed, the concrete trial mixing shall be carried out according to the requirements of the materials and construction methods adopted on site. According to the test results to adjust the construction mix ratio, as a guide to the construction mix ratio.
characteristics of naphthalene series water reducing agent:
1. The main components are β-cai sulfonic acid formaldehyde condensate, sodium sulfate ≤ 5% and 10%, 18% and 23%. There are four main types.
2. good dispersion, reducing water effect is good, early strong effect is good. It can speed up the turnover of formwork and site, speed up the construction progress and shorten the completion cycle. It is suitable for concrete with early strength and high performance requirements to enhance strength and improve long-term performance.
3. Increase the slump of concrete and improve its fluidity, which is suitable for ready-mixed concrete, pumped concrete high fluidity concrete, grouting material, etc.
4. No air leakage. Suitable for all grades of concrete under steam curing and natural curing conditions.
5. Reinforcement shall be free from corrosion. It is suitable for precast concrete, cast-in-place concrete, reinforced concrete soil, prestressed reinforced concrete, etc. in various projects.
Portland cement, ordinary Portland cement, slag Portland cement, fly ash Portland cement and other good compatibility. Fdn-05 and Portland cement, ordinary Portland cement, slag Portland cement fly ash and Portland cement have good compatibility. Key performance and quality indicators.
