Polycarboxylate superplasticizer in the use of more convenient, safe, and efficient, but there are some limitations, the advantage is only relative, so that may be encountered in the construction and production of the following problems. 1, it is difficult discharged from the mixer reasons: It may be polycarboxylate cement and caused severe maladaptive. Approach: each batch of cement should be used in construction before opening likened to a complex test match. 2, the concrete mixture slump abruptly, bleeding causes: the batch of cement and water reducer good adaptability. Approach: admixture dosage should be adjusted. 3, hardened surface bubbles reason: When using in order to facilitate the construction, superplasticizer dosage increase. Approach: in strict accordance with the ratio of construction, improve the construction process, strengthen the construction management. 4, slow setting and hardening of concrete reasons: to increase the dosage of superplasticizer or curing temperature is not enough. Approach: in strict accordance with the reducing agent than construction suppliers, to extend the curing time. 5, concrete slump and design values ??are significantly different reason: Two additive mixed use, occurrence of incompatibility. Approach: do compatibility tests before use, to adjust blending ratio. Comparison and analysis of the performance characteristics of different superplasticizer superplasticizer There are two categories: one is synthetic, single component efficient deceleration agent second is a multi-component composite superplasticizer. Single component, also known as superplasticizer superplasticizer supply Shandong reducing agent, reducing agent for cement and concrete reinforcing effect is very obvious, but often difficult to meet a variety of work of the special properties of hardened concrete and fresh concrete requirements, so now works for a small number of direct and replaced with composite superplasticizer. In the production segment production to meet early strength concrete, air entraining requirements, generally chosen complex multicomponent superplasticizer.
