“…Therefore, the principal component analysis method is used to extract the factors with a characteristic value greater than 1 after the maximum variance rotation. It is found that only one factor can be extracted, and the explained variance ratio is more than 60%, indicating that each measurement item can better measure the corresponding latent variables and has good structural validity [ 23 , 24 ]. On this basis, this paper tests the combined validity and discriminant validity, as shown in Table 3 .…”

In order to solve the problem of resource ecological compensation, this paper proposed a model of resource ecological compensation mechanism based on a rural leisure sports environment. The model is carried out in many places in China. The survey data involves 31 provinces, 10 years, and 43 indicators, with a total of 43 × 10 × 31 = 13,330 data. The preliminary basis of mechanism construction is summarized from four aspects. Finally, make full use of modern information technology to improve the network platform of the compensation mechanism, promote the efficient allocation and comprehensive utilization of ecotourism resources, and lay a solid foundation for establishing a reasonable and perfect resource ecological compensation mechanism and ensuring the long-term and stable operation of the mechanism. Through the experiment, it is found that the timely and effective publication of information can eliminate the inner estrangement between the two sides, so as to make the behavior of both sides more rational. A special information feedback department is established to deal with the opinions put forward by all compensation parties in tourism development, extract effective information, summarize and publish reasonable guidance information, and guide the compensation of both sides to an ideal balance through the feedback of this information. The effectiveness of the experiment is verified.

“…Owens [12] goes on to explain that the compressive strength is calculated by dividing the maximum uniaxial load that can be carried by the concrete with the laboratory specimen's cross-sectional area. e cube and core test are the most widely used testing methods for determining the compressive strength of concrete, while the flexural strength test and tensile splitting test are used to calculate the tensile strength [15,42]. e flexural strength test consists of exposing concrete beam samples to either two loads located at third points or an individual load placed at midspan [12].…”

“…Alternate binder systems are often used to improve the durability, along with the fresh and hardened state properties of concrete exposed to a chloride laden environment [13]. It has been well documented that the use of an alternative binder reduces the cement content thereby reducing the heat of hydration, while also improving the durability by reducing the permeability and thus improving concrete's resistance to chloride attack [13][14][15].…”

Changing human lifestyle and increasing urbanisation are contributory factors to the high demand for concrete construction materials across the globe. With the imminent developments in the unpopulated marine/coastal zones, higher installation of concrete facilities is still expected. However, poor design and construction procedures coupled with inadequate materials selection and exposure to aggressive environmental conditions, such as chloride laden environments, often result in the reduced aesthetic and structural performance of concrete. Deterioration of reinforced concrete structures located in a coastal/marine setting can influence the safety, economic, and sustainability aspects of society. Hence, there is an increased need for alternate binder systems with the ability to reduce the effects of chloride attack in concrete. This paper presents a critical review of the engineering properties of metakaolin (MK) based concrete exposed to chloride attack. The key advantages and limitations of using MK for concrete production purposes were outlined and evaluated. Areas for future research were also highlighted in this paper. Based on the favourable 28-day compressive strength (73–84 MPa) and durability performance documented across the numerous past year studies that were reviewed, it can be concluded that MK is a viable alternate binder material for combatting chloride attack in coastal/marine concrete structures. This, in conjunction with its lack of chemical CO2 emissions, proves that MK can be used to improve the serviceability and sustainability states of marine structures. The viewpoint of this review will guide concrete constructors and researchers on a possible framework for the utilisation of metakaolin for enhancing durability concrete in aggressive environments.

“…Based on the condition of the Simpang Pintu -Benakat road, Penungkal Abab Lematang Ilir (PALI), it is necessary to build a road that accommodates the load that traverses the section, using concrete/rigid pavement (Rigid Pavement) (Rasol et al, 2020). Concrete/rigid Pavement (Rigid Pavement) is a pavement construction with a binding material in the form of cement with a continuous and continuous type of concrete slab, as well as using or without reinforcement located on the subgrade or part of the foundation layer (Pillay et al, 2021;Chore & Joshi, 2020).…”

The access section to Benakat Village, Pali Regency is a special road made by the company, with the condition of the existing land being unpaved with a length of 1,375 meters and a width of 7 meters, and has severe damage triggered by vehicles with excess capacity or ODOL (Over Dimension Over Load)) that pass through that path. The purpose of this study was to determine the results of the calculation of rigid pavement thickness planning by comparing the 1993 AASHTO and 2017 MDPJ methods so that the road Sp. Doors – Sp. Benakat is able to accommodate ODOL vehicles. This study uses AASHTO 1993 and MDPJ 2017 as methods to produce rigid pavement thickness (Rigid Pavement) so that ODOL vehicles can pass. Based on the results of data analysis and calculations, the input indicators in each method are different for each method so that AASHTO 1993 produces a thickness of 35 cm, and in MDPJ it produces a thickness of 28.5 cm
