Introduction

HP series waterproof agent of concrete admixtures meet national building materials industry standard JC474-2008 quality requirements of its mechanism of action is through the reduction of water, air entraining action to reduce the free water content inside the concrete and produce a large number of small bubbles play dense slight barrier and Savings free water to avoid the formation of free water escaping outward passage criss arising penetration; and products in the chemical composition and hydration of the cement produced in the retarding effect of making the process of reducing the condensation heat of hydration and hydration postponed thermal peak time and temperature to avoid the formation of cracks in the construction and form a gel in the internal structure of the solid matter closed Kong Daocheng as a whole so as to achieve water impermeability purpose; in MP-KF product also joined the slight swell components and anti- split component to make concrete with crack waterproof; widely suitable for exclusion to impermeability, anti-leakage, such as concrete foundation slab construction, underground engineering, civil air defense projects.

Model & Main Technical index

Using methods and precautions

1 pumping type waterproof agent for any anhydrite, gypsum do Coagulator cement. Required Note chapter its adaptability.

2 In the initial use or cement variety is changed with a trial ahead of the best, choose the best dosage.

3 concrete mix in fly ash, slag and other active when admixture, water reducing agent dosage should be calculated in the total cementitious material.

4 concrete admixture products of this series should be vibrated dense, final setting supra note shield secondary plaster, after the final setting to warm water conservation.

Packing, transportation, storage

1. HP series powdery waterproof agent with external woven bag, plastic bag Packing. Should pay attention to rain, water, moisture in the intact condition Storage Shelf life is 2 years. Expired products should redo the concrete test qualified before use .

2. HP series liquid waterproof agent: drum or tank car. Should pay attention to rain, water in the original sealed Packing cases, 0 ° C for more than Storage6 months. Expired products should redo the concrete after passing the test before use.

3. HP-KF slight expansion intact composite waterproof agent in Storage conditions Shelf life is 1 year. Expired products should redo the concrete after passing the test before use.

Description: According to the actual requirements of users and works, and sometimes demand specific formulations HP series waterproof agent, according to project specific requirements, the actual use of raw materials as well as the specific conditions of the site to determine dosage and formulations production, in order to bring the best of the concrete quality and the best value for money.

HP high efficient expanding agent

Introduction

This product is made from high quality aluminum clinker, anhydrite and other specialty inorganic materials mixed together by a certain percentage from the new high ground cracking concrete expanding agent, Product Index meet the building materials industry standard CB23439-2009 "Concrete expanding agent" requirements, with a small dosage, rate of expansion, cracking impermeable strong function, low alkali content, slump loss, can reduce the heat of hydration of concrete on concrete strength of small, high-performance anti-Sulfate erosion, and other admixture good compatibility and other unique advantages, is a safe, good durability performance concrete expanding agent.

Main performance and Technical index

1 This product Appearance was gray powder, non-toxic, does not stink. Flammable, non-corrosive.

(2) The product dosage generally 8-10% within the mixed (in terms of total cementitious materials), different purposes according to Table 1 to select ash, mixed with 8-10% expanding agent of concrete when reinforcement was 0.2 -1.0%, the limit expansion rate of 2-4% x 10-4, in the concrete to create 0.2-0.8MPA white Stress Value, when used at the recommended dosage, 28 days compressive strength of concrete and reference concrete roughly the same, The late strength continued to grow. mixed concrete limit strength of this product relatively free high intensity 10-15%. mortar mixed with the product label or the impermeability of concrete up to more than S20, antifreeze capacity of up to more than D200 This product is on No corrosion steel, suitable for common silicate cement.

Use

1 This product dosage depending on the table selected engineering purposes (total and by cementing material calculation)

(2) The product of mixed concrete mix design and construction shall comply with GB50119-2003 "Concrete Admixtures application technology specification" requirement, the minimum amount of concrete cement material shall meet the standards of this product should be cast together with other raw materials of concrete, appropriate extended mixing time 30-60 seconds. should strengthen conservation efforts, to be watered immediately after the concrete to harden. moisture conservation time shall not be less than 14 days in winter pouring concrete or mass concrete must be insulated, moisture conservation.

3 can be used with other concrete admixtures, such as water reducing agent, pumping agent, retarding send water reducing agent, Early strength water reducing agent such as composite use, application better.

4 This product is mixed with concrete for structural waterproof construction, should strengthen the construction vibrators, vibration does not leak, excessive vibration in the final setting of concrete repeated wiping pressure to prevent subsidence cracking.

5 normal circumstances can be taken with the same amount of cement, but due to the different coefficients of surplus cement strength differences, the use of the actual concrete expanding agent to be tested to determine the substitution rate.

Scope

Where the requirements crack, seepage, joints, filling with concrete or cement products, can be associated with the FDA. Particularly suitable for underground structures such as subway, underground parking, underground warehouses, Lu Tao, mining and air defense engineering, construction, swimming pools, water towers, silos and other large containers, from impermeable rigid roof, mortar and moisture vapor barrier housing, and post-tensioned concrete structures and mechanical equipment foundation grouting secondary casting and so on.

Packing storage

1 This product is plastic bag lined woven bag bag weighing 50 kilograms. Library should be stored in a dry, non-moisture, rain and water.

(2) The product was dried under Storage Shape for 1 year, extended by the test can still be used for certification of
