1 individual agency agreement calcium ligno sulfonate and erect agreement after-effects appearance that the optimum altitude for the amalgam of the amino acerbic superplasticizer are: phenol and amino acerbic molar arrangement of 1.5:1, the antecedent acknowledgment arrangement pH amount of 8.5, abstract time was 5h, (phenol + amino acid) with a molar arrangement of 1.25 formaldehyde, formaldehyde was added dropwise time 60min, a band-aid of formaldehyde, the temperature 70 ℃, the abstract acknowledgment temperature is 95 ℃. Actinic application the aloft action altitude different calcium ligno sulfonate superplasticizer content. By ζ potential, adhesive fluidity, artificial beach alteration and abbreviation agent, such as bleeding bulk achievement analysis, the agreeable of lignin sulfonate modified articles is the best time 30wt%.
Foreword calcium ligno sulfonate is a byproduct of sulfite pulping process, are anionic surfactants, as accurate baptize reducer, can save cement, concrete workability and backbone increase, but appliance excessive, will be retarding the accurate stronger, and aftermath a lot of bubbles, consistent in decreased backbone of concrete, can could cause serious or even engineering accident, clumsy to accommodated the requirements of high-performance concrete, Calcium ligno sulfonate based lurid decay as raw material, assimilation and aerosol dehydration and made it accomplished performance, low price, as accustomed water, applications are absolutely common. However, due to the actuality of water-reducing rate, retarding able and cited college gas defects, it has some limitations in the application, abnormally in the dosage is large, so that the gas agreeable of cement-based abstracts increased significantly, acuteness alone significantly, authoritative it difficult to accommodated the requirements of engineering.
Therefore, the modified calcium lignosulfonate has been a concern. In this paper, amino acerbic and amino acerbic as the capital raw material, Calcium lignosulphonate is the second most abundant natural, namely calcium lignin sulfonate superplasticizer (CL) was adapted to actuate the optimum acknowledgment action by erect able two adapted copse Su calcium sulfonate superplasticizer (ACL, CCL).
