Embodiment 1

[0016] An anti-efflorescence process for landscape stone decoration, comprising the following steps: adding a calcium hydroxide consuming agent when pouring concrete structures, the calcium hydroxide consuming agent includes natural volcanic ash and artificial volcanic ash and further reacts with calcium hydroxide to form calcium silicate and silicon Calcium acid itself is insoluble in water, so it will not be brought to the surface of the structure by water through the capillary pores. At the same time, the hardening speed of concrete is delayed, carbon dioxide in the air enters the structure, and calcium hydroxide reacts inside the structure to form solid calcium. After the structural layer is completely dry, carry out waterproof treatment. Carry out six-sided protective treatment on facing stones. Silicone-type protective agent or fluorine-silicon protective agent can penetrate into facing stones and block the pores of facing stones. The surface layer of facing stones is pr...

Embodiment 2

[0018] An anti-pan-alkali technology for landscape stone decoration, comprising the following steps: controlling the brick humidity to 60%-90% when pouring bricks in the brick wall structure layer. After the structural layer is completely dry, carry out waterproof treatment. Carry out six-sided protective treatment on facing stones. Silicone-type protective agent or fluorine-silicon protective agent can penetrate into facing stones and block the pores of facing stones. The surface layer of facing stones is protected from water by film-forming protective agents. . The facing stone is then installed on the concrete structural layer. Then close the permeation channels between the facing stones. After the top facing stones are grouted and installed in place, clean up the mortar in the stone joints, seal all the gaps with silicone sealant, and seal the stones before the side stones are grouted. Strictly seal the inside and outside of the seam with glue.

Abstract

The invention discloses a saltpetering resisting technology for a landscape stone decorative finish. The saltpetering resisting technology includes the following steps of (1) conducting treatment on a structural layer, specifically, the structural layer comprises a concrete structure and a brick-wall structure, the concrete structure is formed by adding a calcium hydroxide consumption agent in concrete, and the brick humidity is controlled to 60%-90% in the brick pouring process of the brick wall structure; (2) conducting waterproof treatment after the structural layer dried out; (3) conducting six-face protection treatment on decorative finish stones, specifically, a protective agent permeates in the decorative finish stones to block pores of the decorative finish stones, and conduct watertight protection on the face layers of the decorative finish stones; (4) mounting the decorative finish stones; and (5) sealing permeating channels among decorative finish stones, cleaning mortar in edge joints of the stones after completing mounting of shoving of coping decorative finish stones, using a joint mixture material with good impermeability to seal all of gaps, and conducting strict glue sealing on the inner portions and the outer positions of the edge joints of the stones before conducting grouting on side stones, and accordingly the landscape stone decorative finish can be prevented from saltpetering.

Description

technical field [0001] The invention relates to a landscape technology, in particular to an anti-pan-alkali technology for landscape stone decoration. Background technique [0002] Pan-alkali refers to the main component of concrete, calcium silicate (weak acid and strong alkaline salt), which undergoes hydration reaction after contact with water to form free calcium, silicic acid and hydroxide. When there is enough water in the concrete, under the action of capillary pressure, the water will flow out, and at this time, free calcium, sodium, potassium and other substances will flow out with water as the carrier. After reaching the surface of the stone, as the water evaporates, these substances remain on the surface of the stone, forming white powdery crystals, or reacting with carbon dioxide in the air to form white lumps on the surface of the stone. These white substances formed are commonly known as ubiquinol. Contents of the invention [0003] The object of the presen...
