Question 1: What is marl lime soil? It is a soil with limestone as its parent material developed in the subtropical region of southern China. Generally, its texture is relatively heavy, and there is more or less lime foam reaction on the profile, but the soil color is different. There are four common types: red, yellow, brown and black. This is a section of brown calcareous soil shot in Guiyang, with a thickness of 50 cm. The topsoil is grayish brown, gradually changing from dark reddish brown to light reddish brown, and the bottom layer is light purple gray limestone parent layer. This soil is widely distributed in Guangxi, Guizhou, Yunnan and other provinces. It belongs to calcareous soil. Description of soil properties: Lime (rock) soil is a kind of soil developed on weathered carbonate rocks in tropical and subtropical regions. Most of them are clay, with high soil exchange capacity and base saturation, and clear transition between soil and bedrock surface. Lime (rock) soil can be divided into four subcategories, all of which are distributed in this area. The subclasses of red calcareous soil are mostly developed in the ancient weathering crust of thick limestone, which is the calcareous (rock) soil with the strongest weathering and leaching and the deepest decalcification. The soil has no lime reaction and the pH value is neutral. Black calcareous soil is a kind of A-R soil scattered between rock cracks and peaks in karst areas. The black humus layer is 20-40 cm thick, with 5-7% organic matter content, low decalcification degree, and the soil reacts with lime and is weakly alkaline. The subclass of brown calcareous soil is between the first two, and there is no lime reaction or weak lime reaction; The subclass of yellow calcareous soil is distributed in mountainous areas above 800 meters above sea level, and is often interlaced with yellow brown soil or yellow soil. Soil has yellowing characteristics and neutral reaction.

Short for lime soil. It is characterized by its plate-like nature and higher strength than gravel pavement. It has certain water stability and frost resistance, and its initial strength is low, but its long-term service strength increases with age. Shrinkage, easy to crack; Lime granular materials are suitable to be used as the base of secondary roads and urban secondary roads, and can also be used as the subbase of highways at all levels. Lime soil is not suitable for wet road sections;

I hope I can help you. Have a nice day ~

Question 2: the difference between marl and peat soil;

1. Different air permeability:

Peat soil is often used for the cultivation and conservation of flowers because of its good air permeability. Ordinary soil can't meet this requirement.

2. Strata areas are different:

Peat soil refers to the soil in some lowlands and valleys deposited in rivers and lakes. Due to long-term water accumulation and dense aquatic vegetation, a large number of incompletely decomposed plant residues accumulate to form peat layer under anoxic conditions. Soil is soil, which is the loose surface of the earth's land surface. It has certain fertility and can grow plants. It is formed and developed by weathered rocks under the comprehensive action of biology, climate, topography and other factors.

3. Different components:

Peat soil is soft and garden soil is hard. Commercial soil is generally prepared soil, mostly soft soil composed of coconut bricks and slow-release fertilizers. It is usually composed of trees, sedges, sphagnum and other plants that make carbon, thus forming peat. The composition of soil includes minerals, organic matter, moisture and air.

Question 3: What is lime-soil foundation? Lime-soil foundation is a foundation with certain strength, water stability and impermeability, which is made by digging soft soil in the required range below the bottom surface of the foundation, fully mixing with a certain proportion of lime and soil at the optimal water content, and backfilling and tamping in layers.

Question 4: What is the mixture of lime+clay+crushed stone in a certain proportion? It is called lime-soil gravel. Generally used as a cushion.

Question 5: What is the main composition of lime soil? Please be more specific. Thank you. Lime soil is generally a general term for composite soil, which is divided into several compensation components, usually including:

Lime-flyash soil generally refers to the compound of lime and soil, and its composition is mostly (2: 8 or 3: 7).

Concrete refers to the mixture of lime, fly ash and soil.

Cement lime-soil generally refers to the compound of cement, fly ash and soil.

Question 8: What is lime-soil solidification? If the foundation of the building is treated with lime soil, there is no need for maintenance, and it can be backfilled and compacted directly.

If it is the ash floating base of the road surface, if it needs maintenance, it should be maintained by sprinkler to keep the surface dry and wet, and the maintenance time is 7 days.

Question 9: The formation of calcareous soil is deeply influenced by parent rock. Limestone is easily eroded and weathered in tropical and subtropical warm and humid environments. Fresh limestone products, disintegrated fragments and surface water containing carbonate continue to enter the soil, which delays the leaching and desilication of salt-based components in the soil and keeps calcareous soil in the bud.

Question 10: Can it be muddy and dusty to raise small water lilies? You mean soil like plant ash? Generally, garden soil and the like can be used.
