Detail

　　Product Description

　　Sumiling No.1 is a high‑performance concrete designed for modern high‑performance construction and special engineering projects,based on micro fiber reinforcement technology.By incorporating high‑strength micro steel fibers and special active admixtures,it delivers high strength,excellent toughness,superior durability and good workability after curing.

　　Product Features

　　Ultra‑early strength&fast traffic opening

　　It typically achieves high early strength(compressive strength>30 MPa)within 2–4 hours,meeting the basic requirements for opening to traffic.It greatly shortens road closure time and reduces social traffic and economic impacts caused by construction.It is especially suitable for“window‑period”projects requiring nighttime construction and traffic reopening in the early morning.

　　High bonding strength

　　Its bonding strength to existing concrete substrates is much higher than that of conventional concrete.It integrates well with the original matrix to bear loads jointly,with high fluidity and self‑compacting properties,effectively preventing delamination,voids and debonding of repair layers.

　　Excellent durability

　　It features outstanding impermeability,freeze‑thaw resistance and salt‑alkali corrosion resistance(anti‑abrasion).It can maintain stable long‑term performance in severe cold regions,coastal areas and repair structures without damage caused by freeze‑thaw cycles or salt corrosion.
