“…Therefore, the application effect of polymer particles in cementing cement slurry before and after modification was evaluated. The compressive strength is the maximum external force that the cement stone can withstand when it is damaged; the cement stone needs to withstand the horizontal compressive force of the formation pressure and the vertical tension caused by the casing [ 32 , 33 ]. A cement sample needs to have a good compressive strength to support and protect the casing.…”

The integrity of oil well cement sheaths is closely related to the long-term production safety of oil and gas wells. The primary material used to form a cement sheath is brittle. In order to reduce the brittleness of oil well cement and improve its flexibility and resistance to stress damage, nano-silica was used to modify polymer elastic particles, and their properties were analyzed. The influence of the modified polymer particles on the properties of oil well cement-based composite materials was studied, and the microstructure of the polymer particle cement sample was analyzed. The results showed that nano-silica effectively encapsulates polymer particles, improves their hydrophilicity, and achieves a maximum temperature resistance of 415 °C. The effect of the modified polymer particles on the compressive strength of cement sample is reduced. Polymer particles with different dosages can effectively reduce the elastic modulus of cement paste, improve the deformation and elasticity of cement paste, and enhance the toughness of cement paste. Microstructural analysis showed that the polymer particles are embedded in the hydration products, which is the main reason for the improvement in the elasticity of cement paste. At the same time, polymer particle cement slurry can ensure the integrity of the cement sample after it is impacted, which helps to improve the ability of oil well cement-based composite materials to resist stress damage underground.

“… 41 The current curing technology uses a binder that is usually cement. Still, cement has limited compatibility with soil, and materials superior to cement are often more expensive, 42 so curing technology is challenging to be applied to actual contaminated sites.…”

“…Consequently, its compressive strength remained constant or slightly decreased after 28 days due to carbonation shrinkage. Chaiyaput et al [43] mentioned that the UCS of soil-cement samples cured under limesaturated water showed a higher rate of hydration process, resulting in the highest UCS in comparison with those cured under tap water, plastic wrapping, and open ambient at 28 days. In addition, an elevated curing temperature remarkably improved the early UCS gain and longterm performance [44].…”

“…In this review, the authors will specifically focus on three key properties: compressive strength, tensile strength, and elastic modulus. These properties of cement-treated soil have been intensively assessed in previous studies [1][2][3][4][5], and they are influenced by various factors, including soil types, cement content and type, curing period, curing condition, and even compaction method [6][7][8][9]. For example, a previous study investigated the effect of cement type on the strength evolution of cement-treated soils under different curing temperatures and found that cement type strongly affected the compressive strength of cement-treated soils [10].…”

The use of cement-treated soil is a crucial and traditional method for stabilizing soft ground and the bases or sub-bases of road pavement. However, due to the variable characteristics of soil worldwide, there is no precise design for the mixture proportion of cement-treated soil. This review paper aims to summarize the existing research to identify the main factors influencing the mechanical characteristics of cement-treated soil, specifically unconfined compressive strength (UCS), tensile strength, and modulus of elasticity. The compressive strength of cement-treated soil is governed by many key factors such as cement content, cement type, compaction type, curing time, and curing condition. The UCS of cement-treated soil shows improvement with increased cement content and curing period, and various prediction models for UCS development are summarized and reviewed. Additionally, this review covers methods for estimating tensile strength and modulus of elasticity based on UCS. Besides, microstructure investigation is also mentioned to comprehensively provide evidence for the explanation of strength development.
