Abstract
The invention discloses a high efficiency concrete composite admixture, which comprises the following components: by weight, 5%-20% of triethanolamine, 10%-15% of sodium lignin sulfonate, 2% - 3% of a naphthalene-series high efficiency water reducer, 1% - 2% of bone glue, 5% - 15% of tartaric acid, 2% - 3% of rosin, 3% - 5% of sodium dodecyl benzene sulfonate, and the balance of water. The high efficiency concrete composite admixture has the advantages of simple process and excellent performances.
Description
Technical field
The present invention is specifically related to a kind of multifunctional concrete admixture.
Background technology
In order to improve and to regulate concrete performance, how therein Mixed With Admixture.But existing concrete admixture function singleness, as need improve multiple performance, often volume is larger.
Summary of the invention
To the object of the invention is the defect existing in prior art in order solving, a kind of concrete admixture with multiple efficacies to be provided.
In order to achieve the above object, the invention provides a kind of high-effective concrete compound additive, by following compositions in weight percentage, formed:
Trolamine 5%-20%,
Sodium lignosulfonate 10%-15%,
Naphthalene series high-efficiency water-reducing agent 2%-3%,
Gelatine 1%-2%,
Tartrate 5%-15%,
Rosin 2%-3%,
Sodium dodecylbenzene sulfonate 3%-5%,
All the other are water.
Optimum ratio is:
Trolamine 10%,
Sodium lignosulfonate 12%,
Naphthalene series high-efficiency water-reducing agent 2.5%,
Gelatine 1.5%,
Tartrate 10%,
Rosin 2.5%,
Sodium dodecylbenzene sulfonate 4%,
All the other are water.
The present invention has the following advantages compared to existing technology: utilize tartrate delay concrete initial set and final setting time and do not affect late strength of concrete, simultaneously with sodium lignosulfonate and the composite use of naphthalene series high-efficiency water-reducing agent, can effectively improve water-reducing rate, improve concrete pumping; Utilize gelatine, rosin and Sodium dodecylbenzene sulfonate can effectively improve concrete frost resistance, impermeability and weather resistance; Utilize trolamine can effectively improve concrete ultimate compression strength.High-effective concrete compound additive technique of the present invention is simple, excellent property, after using, improve concrete workability and reduce segregation, reduce bleeding quantity, improve homogeneity, reduce or avoid aggregate sedimentation to regulate time of coagulation, solve high temperature concrete manufacture difficulty, improve pumping, be easy to concrete Construction of High-rise, delay or reduce hydration heat, improve early stage or later strength, compensate for shrinkage or microdilatancy, reduce dry shrinage and slow change, improve the cohesive force of the good reinforcing bar of concrete, the action of rust that stops built-in metal, significantly improve concrete freeze-thaw resistance and watertightness, also increase the ability of certain chemical resistance of concrete simultaneously.
