Abstract
The invention discloses a high efficiency concrete water reducing agent comprising a naphthalene-series high efficiency water reducing agent and a calcium lignosulfonate water reducing agent; the weight ratio of the naphthalene-series high efficiency water reducing agent to the calcium lignosulfonate water reducing agent is 1:1-2.5. The high efficiency concrete water reducing agent uses the naphthalene-series high efficiency water reducing agent and the calcium lignosulfonate water reducing agent for compounding, can effectively reduce production costs, and improves the water reducing ratio.
Description
Technical field
The present invention relates to a kind of concrete high efficiency water reducing agent.
Background technology
Water reducer refers under concrete workability and the constant condition of cement consumption, can reduce mixing water amount, improve concrete strength; Or under workability and intensity permanence condition, save the admixture of cement consumption.China's turnout is maximum at present, and using the widest high efficiency water reducing agent is naphthalene water reducer.But naphthalene water reducer cost is higher.
Summary of the invention
To the object of the invention is the defect existing in prior art in order solving, the high efficiency water reducing agent that a kind of cost is low to be provided.
In order to achieve the above object, the invention provides a kind of concrete high efficiency water reducing agent, comprise naphthalene series high-efficiency water-reducing agent and calcium lignin sulfonate water depressor; The weight ratio of described naphthalene series high-efficiency water-reducing agent and calcium lignin sulfonate water depressor is 1:1-2.5; Described calcium lignin sulfonate water depressor is prepared by following steps:
1) get liquid waste of pulping by sulfite process and be concentrated into 1/3rd of original volume, add sodium hydroxide to regulate pH value to 8-10, pass into after air reacts 10h at 75 ℃ and obtain reaction soln;
2) to the sodium sulfate adding in the reaction soln of preparation in step (1) with the quality such as described sulphite process spent pulping liquor, replacement(metathesis)reaction 45min at 75 ℃, filters, and obtains described calcium lignin sulfonate water depressor after dry.
Wherein, naphthalene series high-efficiency water-reducing agent and and the preferred weight ratio of calcium lignin sulfonate water depressor be 1:2.
The present invention has the following advantages compared to existing technology: utilize naphthalene series high-efficiency water-reducing agent and calcium lignin sulfonate water depressor to carry out composite, can effectively reduce production costs, improve water-reducing rate.The preparation technology of calcium lignin sulfonate water depressor of the present invention is simple, and few with the precipitation of the composite rear generation of naphthalene series high-efficiency water-reducing agent.
