Problems solved by technology

The two-liquid method with silicate as the main component dissolves highly alkaline substances, and at the same time, it will cause a phenomenon of low strength over time, so it is not ideal.
Moreover, the method using a high molecular compound also causes environmental pollution problems and does not have wide practicability

Embodiment Construction

[0038] The method of using the improver of the present invention is to mix cement into the soil at the construction site, then add SC-100 made into an aqueous solution for stirring, and then roll and compact it to make SC-100 penetrate into the roadbed together with cement , to realize the complete combination of roadbed and land. In this way, the load on the land and roadbed is distributed to a reasonable state, so that it can withstand vibration and long-term loads, and at the same time, the strength of bending and tension is increased by 20-30% compared with the previous manufacturing method. After rolling and compacting for a period of time, the land has the characteristics of strengthening year by year, because it can also harden in water, and the water resistance after rolling and compacting is also enhanced, so it will not be affected by the weather.

[0039] After adding the SC-100 aqueous solution composed of various inorganic metal elements to the soil, through the h...

Abstract

The invention relates to a groundwork curing and soil property improving agent, developed for curing the soil and simultaneously achieving long-term stability. Its components are inorganic metal elements, thus having no problem of environmental pollution. Whether in soil property or sea water, it has the properties of curing in water, freeze resistance and high-temperature resistance. It also absorbs the advantages of previous method of maming cement-earth mixture, overcomes the disadvantages, like curing contractility, freeze-thaw resistance and fragility. It cures year by year, therefore it is uneasy to age and be eroded by acids or alkalis. It can directly use the earth on the spot without sand and other raw materials and has characters of short construction cycle and environmental protection.

Description

Technical field: [0001] The invention relates to a method and an improving agent for ground hardening and soil quality improvement through a compound composed of inorganic salts, and belongs to the technical field of international patent classification C09K17 / 00 "soil conditioning materials". Background technique: [0002] Regarding the hardening and improvement of foundations such as sand, silt, gravel, organic soil, pozzolanic clay peat, etc., in the civil engineering, construction industry and many other industries, the hardening method used in the past is well-known. method. Cement and concrete production methods (soil + cement + water) have poor coagulation power, are prone to aging, and will also affect soil quality, especially when organic soil and humus soil contain substances that hinder cement hardening. Lime-like substances, its long-term stability is not as good as cement. On the other hand, as construction methods that do not use gravel, etc., there are also t...
