How to choose a building fastener

With the rapid growth of the construction industry, many building materials, components, and accessories have become common products that people purchase. When it comes to choosing construction fasteners, manufacturers often emphasize that quality should be the top priority. One of the key factors in assessing the quality of construction fasteners is their hardness. To determine this, it's important to compare them with lower-quality alternatives and check the steel content of the product, as higher steel content typically indicates better durability and strength. Additionally, it’s advisable to consider whether the product comes from a reputable and well-established construction company, as they are more likely to maintain high standards.

Choosing the right fasteners is crucial for ensuring the safety and longevity of any construction project. Whether you're working on a residential or commercial site, using substandard fasteners can lead to structural weaknesses and costly repairs down the line. Always take the time to evaluate the quality of the fasteners you're purchasing, and don't hesitate to ask for certifications or samples if needed. Investing in high-quality fasteners today can save you time, money, and potential headaches in the future.

Auxiliary Agent For Concrete Retarder

Classification by structure:
(1) Sugar: sugar calcium, gluconate, etc
(2) Citric acid, tartaric acid and their salts
(3) Zinc salt and phosphate
(4) lignosulfonate
Hardening effect
(1) Influence on strength, excessive incorporation will cause the concrete to remain unsolidified for 24 hours or even 72 hours, thus affecting the need for early strength of concrete and delaying the construction progress. No obvious effect was found on the concrete of suitable age.
(2) The effect on contraction, the appropriate use of the contraction has no significant effect. Excessive use will cause the top concrete to dry and shrink due to excessive water evaporation and shrinkage cracks.
(3) The effect on frost resistance durability is similar to that of concrete without adding retarder. [1]
