Abstract
The invention discloses a super retarder which is composed of the following components in percentage by weight: 2-3% of calcium lignosulphonate, 3-4% of naphthalene high efficiency water reducing agent, 5-6% of sugar calcium, 2-3% of monosaccharide and the balance of sucrose. The super retarder can greatly extend the cement-stable pavement substrate material and delay the molding time on the premise of ensuring later strength.
Description
Technical field
The present invention relates to a kind of extra retarded set material, being specifically related to a kind of super-retarder for extending cement stabilized pavement base material delay in forming time.
Background technology
In order to extend the hydration and hardening time of cement, how in concrete, to mix retardant, making fresh concrete can keep plasticity in a long time, thus regulate the time of coagulation of fresh concrete.The method extensively adopted both at home and abroad at present adds the retardant such as wooden calcium, sugared calcium to extend time of lag, but incorporation is large, high cost, and not easily mix is even.
Summary of the invention
The object of the invention is, in order to solve the defect existed in prior art, to provide the retardant that a kind of cost is lower, loss of strength rate is less.
In order to achieve the above object, the invention provides a kind of super-retarder, be made up of the component of following weight percentage:
Wood calcium 2%-3%,
Naphthalene series high-efficiency water-reducing agent 3%-4%,
Sugar calcium 5%-6%,
Monose 2%-3%,
All the other are sucrose.
Screening formulation is:
Wood calcium 2%-3%,
Naphthalene series high-efficiency water-reducing agent 3%-4%,
Sugar calcium 5%-6%,
Monose 2%-3%,
Air entrapment agent 0.1%-0.2%,
All the other are sucrose.
Optimum formula is:
Wood calcium 2%,
Naphthalene series high-efficiency water-reducing agent 3%-,
Sugar calcium 5%,
Monose 2%,
Air entrapment agent 0.1%,
All the other are sucrose.
The present invention has the following advantages compared to existing technology: by adding water reducer, effectively improving pumpability of concrete, with the use of air entrapment agent, effectively can improve intensity, reducing because postponing the shaping loss of strength caused.Super-retarder prepared by the present invention, under the prerequisite ensureing later strength, can significantly extend cement stabilizing road surface base layer material, delay in forming time, also can be used as concrete retarder, can extend molding time by more than 6 hours.And the raw material that the present invention adopts is easy to get, cost is low, and volume is few, easy to use, can meet the construction requirement of cement stabilized pavement base material completely.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
