Viongezeo vya Zege nyepesi | Mawakala wa Utendaji wa Juu wa Kutoa Mapovu kwa Saruji ya Simu
concrete additive water reducer superplasticizer is a chemical used to make concrete mixtures flow easier. It is available as a powder or liquid and can be added to the mix as needed for desired workability. It works by lowering the water/cement ratio and allowing for higher concrete strength with lower permeability. It may also speed up or retard concrete setting according to its chemical reaction. It can be used in high-performance concrete applications such as pumpability, saruji ya kujitegemea (SCC), low permeability and low water absorption.
Concrete mixes that are mixed with water reducers have a lower slump than those without them. This makes it easier to work the concrete by hand and saves on labor costs. Mchanganyiko wa ubora wa kupunguza maji unaweza kuongeza mdororo wa mchanganyiko wa zege bila kubadilisha yaliyomo kwenye saruji..
Mchanganyiko wa kupunguza maji unaweza kutumika pamoja na mchanganyiko mwingine kama vile seti za kurudisha nyuma., mawakala wa uingizaji hewa, mafusho ya silika na majivu ya kuruka. Michanganyiko hii inaweza kusaidia kukidhi mahitaji ya utendaji wa miradi kama vile safu wima ndefu, slabs za sakafu zenye nguvu nyingi au miundo ya majimaji inayostahimili mikwaruzo.
Mbali na kupunguza maji, viungio vya simiti kama vile viambatanisho vya juu zaidi vinaweza kutumika kwa madhumuni mengine kama vile kuchelewesha seti ya awali ya simiti au kuongeza nguvu yake ya kunyumbulika.. Baadhi zinapatikana kama vichapuzi visivyo na kloridi ambavyo vinaweza kutumika katika simiti iliyopeperushwa mapema au iliyoshinikizwa bila kuathiri vibaya nguvu ya mwisho ya simiti.. Nyingine ni viungio vya kudhibiti unyevu ambavyo huruhusu wakandarasi kupata saruji bora zaidi kwa kudhibiti unyevu na saizi ya chembe ya saruji..
