Puas yog Sandstone haum rau siv hauv tsev?

Sandstone yog ib qho ntawm cov pob zeb uas siv ntau tshaj plaws, feem ntau nyob rau hauv ntau cov kab ke geological thiab yooj yim siv rau kev tsim vaj tsev. Hauv kev tsim kho, lub ntsiab kom zoo dua ntawm sandstone tshaj lwm lub pob zeb yog tias nws tuaj yeem faib tau yooj yim raws nws lub dav hlau deposition siv cov cuab yeej txhais tes yooj yim - thiab lub ntsej muag sib cais yog qhov xav tau ntau heev.

Sandstones sib txawv nyob rau hauv qhov xwm ntawm lawv cov constituent nplej thiab tej zaum yuav txawv nyob rau hauv loj, muaj pes tsawg leeg, zoo, roughness, thiab degree ntawm dissolution.

Cov khoom tuaj yeem raug teeb tsa hauv cov kab sib txawv, thiab qhov zoo thiab hom ntawm cov cement yog qhov sib txawv. Tag nrho cov no cuam tshuam li cas cov xuab zeb tau muab coj los ua ib lub pob zeb loj.

Sandstone tsis yog ib txwm muaj ntau yam pob zeb ntuj, feem ntau yog vim muaj kev txwv los ntawm cov txheej txheem tseem ceeb hauv qab. Qhov twg cov xuab zeb los ntawm cov dej hauv hiav txwv, cov txaj zoo li nyias nyias, thiab cov pob zeb no tuaj yeem tsim qhov tsis muaj zog, txawm tias cov no tuaj yeem siv tau thaum faib cov pob zeb rau hauv paving thiab flooring, thiab qee zaum rau vov tsev.

Sandstone tej zaum yuav muaj qhov zoo dua limestone nyob rau hauv cov tsoos block pob zeb masonry siv vim tias txawm tias cov xuab zeb zoo dua tsis siv rau qhov kev puas tsuaj uas limestone tuaj yeem ua tau (txawm tias feem ntau ntawm kev puas tsuaj rau limestone yav dhau los yuav cuam tshuam rau cov kua qaub nag, tsis yog li ntawd. common lawm).

Tej zaum qhov sib txawv tseem ceeb ntawm limestone thiab sandstone yog qhov tsis muaj kev sib txuas ntawm micropores hauv sandstone, uas txhais tau hais tias lawv nyiam tsis tuav dej ntev li limestone thiab yog li tsis tshua muaj kev cuam tshuam los ntawm Frost.

Tsis tas li ntawd, sandstones zoo li muaj tsawg dua porosity. Qhov no txhais tau hais tias lub pob zeb muaj peev xwm tuav tau dej tsawg dua thiab tsis tshua muaj qhov nce hauv siab vim yog dej khov los yog ntsev crystallizing thiab ua rau tawg lossis lwm yam kev puas tsuaj.

The main disadvantage that sandstone exhibits compared to most other stones is the presence of different types of substrates that can affect various properties. For example, small amounts of carbonate in the matrix can significantly reduce resistance to acidic influences. Many sandstones contain small amounts of clay minerals, which are generally inert but sometimes swell, causing damage under constant cycles of wetting and drying. In some cases, clay-rich inclusions or regions will weather rapidly. 

Unlike many building stones available, it's hard to imagine an environment where sandstone would appear out of place. This may be because sandstone makes up most of our own landscape.

Through a brief exploration of new developments in sandstone design and preparation, as well as the material's inherent environmentally friendly properties, it is clear that sandstone is rapidly becoming the building material of the future. Combined with the timeless advantages of sandstone, including its durability, strength and slip resistance, as well as increasing value over time, sandstone has proven itself to be a versatile and useful stone.
