A superplasticizer is a concrete additive that increases the workability of concrete while also reducing its water content. This makes it easier for workers to mix, pour and finish the concrete, as well as reduces the risk of cold joints in the finished product. Ntxiv rau, the added admixture will improve the strength of the concrete.
Superplasticizers are made up of water-soluble polymer molecules. When mixed with concrete, these molecules attach to the surface of the cement particles. This creates an ionic bond between the molecule and the cement grains. It also reduces steric hindrance, which is the constraint caused by intra or inter-molecular interactions within the molecule.
The global market for concrete superplasticizers is growing rapidly. This is mainly due to the high demand for ready-mix concrete (RMC) hauv cov haujlwm tsim vaj tsev thoob ntiaj teb. Kev thov RMC yuav nce ntxiv nrog kev tsim kho ntau yam haujlwm infrastructure sai sai no.
Txhawm rau ua raws li kev thov nce ntxiv rau RMC, cov tuam txhab tab tom tsom mus rau kev tsim cov pob zeb zoo tshaj plaws nrog kev pab ntawm cov thev naus laus zis siab. Superplasticizers yog ib qho ntawm cov khoom tseem ceeb siv hauv RMC. Cov tshuaj no yog lub luag haujlwm hloov cov pob zeb nplaum tsawg thiab ruaj khov mus ua ib qho khoom uas tuaj yeem ntws tau, cov khoom mos. Lawv kuj pab txo qhov piv ntawm w/c thiab pab txo kev tawg ntawm cov pob zeb nplaum tawv.
Fritz-Pak's KEM SUPLAST 101 S yog ib qho superplasticizer raws li sulphonated naphthalene formaldehyde uas muab cov txiaj ntsig hauv qab no:
