“…The relative density of the red clay was 2.74. The optimal water content and maximum dry density of the red clay were 24.5% and 1.54 g/cm 3 , respectively. The liquid and plastic limits of the red clay were approximately 68% and 31%, respectively.…”

“…Reinforcement has become a relatively common foundation treatment method owing to its low cost and convenient construction. It has been extensively used in civil engineering, water conservation, construction, and other fields [1][2][3]. Coir fibers are more durable than other natural fibers owing to their high lignin content, highest elongation at the breaking point of any natural fiber, and can withstand 4-6 times more strain than other fibers [4][5][6][7].…”

Geosynthetics slowly degrade in soil, which may cause environmental problems in the future. Natural coir fibers are green, environmental-friendly, renewable, and have broad application prospects. Coir geotextiles were used to reinforce red clay foundations. The effects of the reinforcement length and depth, first-layer reinforcement depth, and reinforcement-layer spacing on the deformation and bearing capacity of the foundations were studied via load tests. The distribution law of the earth pressure along the depth was also analyzed. The results showed that when the reinforcement length was 1B, the anchorage length of the reinforcement was insufficient, and the reinforcement effect was unclear. As the reinforcement length increased, the anchoring length of the reinforcement increased, and bearing capacity of the foundation significantly increased. However, when the reinforcement length exceeded 3B, the force of the anchorage segment was fully exerted, slightly increasing the bearing capacity of the foundation. The optimal reinforcement length was determined as 3B. The bearing capacity of the foundation increased as the reinforcement depth increased and the buried depth of the first reinforcement layer and spacing of the reinforcement decreased. The optimal reinforcement depth, buried depth of the first reinforcement layer, and reinforcement spacing were 2B, 0.25B, and 0.25B, respectively.

“…Cocos nucifera is notably important in tropical regions and produces various income-generating products (Prades et al 2016). New developments in biodiesel production and extraction of coconut fibers from husks have been documented (Rasyid et al 2018;Universiti Malaysia Sarawak 2019;Rao et al 2020; Ben University of Applied Sciences 2021; Ignacio and Miguel 2021). These developments are increasingly used in agriculture, civil engineering, and eco-green cities construction (Prades et al 2016;Rao et al 2020).…”

Abstract. Ramos GB, Panduyos JB, Caray RE, Bacquial LS. 2024. Unveiling coastal diversity: An inventory and conservation report of beach forest flora of Surigao del Sur, Philippines. Biodiversitas 25: 421-430. Coastal greenbelts, comprise mangroves and beach forest trees, are pivotal in disaster mitigation and climate change resilience. Despite the evident importance of these coastal ecosystems, they are often overlooked in research due to a lack of comprehensive data on species community structure and their broader ecological importance. Hence, this present study was conducted to document beach forests composition and conservation status in selected coastal municipalities of Surigao del Sur, Philippines. The study was conducted in five sampling locations, namely, La Paz, Bil-at, Balibadon, Poblacion Cagwait and Arangasa Island. At each sampling location, a 2 km transect line, parallel to the beach’s shoreline, was established having a 100 square meter sampling plots spaced 50m apart. Beach species frequency counts, percentages, and diversity indices were quantified. The study documented 27 beach forest species belonging to 21 families and 25 genera with the dominant species being Crinum asiaticum, Cocos nucifera, Millettia pinnata, Timonius compressicaulis, and Terminalia catappa. Both Arangasa Island and La Paz beach forests have the highest species diversity (H’ = 2.04); however, Cagwait has the highest species richness (Margalef = 2.34). This study has potential to significantly contribute in addressing existing data gap regarding beach forest species in the Philippines. With the looming threat of extinction due to infrastructural development and anthropogenic activities, the study's outcomes stand as an urgent call to action; thus, a collaborative endeavor of Local Government Units, academicians, and community for conservation and protection before these species succumb to the threat of extinction.

The present study brought out the effort and quantifies the use of geotextile in Low-Volume Roads over the weak subgrade. The Low-Volume Roads (LVRs) play a key role in the economic growth of rural area as well as helps in developing the country. The construction of these LVRs over the weak strength of soil subgrade is a challenging task for civil engineering to provide the safe and smooth flow of traffic, and such soil is revealed that the Black Cotton soil (BC). The weak soil subgrade consists the finer particles like clay and silt showing poor shear strength, bearing capacity, and California bearing ration values. It poses several serious problems to the LVRs. To arrest these problems many of the conventional techniques were adopted in pavement application. But these techniques are nor economical and neither eco-friendly. To reduce this problem, the cost of construction, and to provide a longer duration, geosynthetics are introduced as an alternate material in pavement application in the last few decades. In the umbrella of geosynthetics, the geotextile is gaining attention for its utilization in pavement constructions. The study found the coir composite mats performed better reinforcement and improved the strength of the pavements. This study concluded that the use of coir geotextile mats with appropriate of sub-base soil at the suitable position at H/4 with morrum soil improved the performance of the LVRs with 200mm thickness of mould over the 400 mm thickness of the mould. It is indicate a decrease in construction and maintenance costs of the LVRs.
