In this study, marine clay will be studied by mixing lime and cement in order to determine the strength development especially under ponding condition. The sample is classified based on AASTHO and USCS classification systems by using the Atterberg limits test (liquid limit and plastic limit) and the sieve analysis test, whereas Unconfined Compressive Strength (UCS) and the California Bearing Ratio test (CBR) were conducted to determine the strength before and after adding different percentages of lime and OPC cement.
Treating marine clay is important for further purposed in construction and other infrastructure. Marine clay is considered as soft clay that can not resist heavy load and it found both in the littoral and in a few seaward ranges. The objective of this study is to determine physical and engineering properties of marine clay collected from Kuala Perlis, Malaysia, to investigate the improvement of strength of marine clay treated with lime and cement and investigate the long term effect of lime and cement in treatment marine clay under ponding condition.

Excerpt from the Book
1.1 Research Background
Between the past and the present soil is the main element in any construction. Right from the ancient times people used to build their huts and houses in solid soil layers. However, in order to follow-up the urban development the mankind started to build even in a very soft soil layer by treating these layers. Lime and cement nowadays are widely used as a treatment to increase the stability of soft clayey such.
The firmness of the underlying soils is the long-term performance of any construction project depends on. Unstable soil can produce substantial problems for structures or road pavement. With proper design and construct techniques such as lime and cement treatment transforms the unstable underlying soils to stable layers. Indeed, the structural strength of cement-stabilized or lime-stabilized soils can be factored into pavement designs (Ibtehaj et.al, 2014).
Lime and cement stabilization utilized to be factored to enhance soils to varying degrees, depend upon the target. The least quantity of treatment is utilized to temporarily modify or dry soils. Such a small treatment could makes a functioning underlying soil for temporary roads or structure, a greater degree of discourse that can be examine, invention, and proper construction techniques can produces long-term structural stabilization of soils (Ibtehaj et.al, 2014).

Frequently Asked Questions
What is the primary focus of this research?
The research focuses on the strength development of marine clay collected from Kuala Perlis, Malaysia, when treated with lime and cement stabilization agents.
What are the core themes addressed in this work?
The work addresses soil mechanics, classification systems, ground improvement techniques, and the long-term behavior of treated soils under submerged or ponding conditions.
What is the main research objective?
The objectives are to characterize the marine clay, investigate the strength improvement after lime and cement treatment, and evaluate the long-term effects of these treatments under ponding conditions.
Which scientific methods were employed?
The study utilizes laboratory tests including Sieve Analysis, Atterberg Limits, Unconfined Compressive Strength (UCS) tests, and California Bearing Ratio (CBR) tests.
What does the main body cover?
The main body covers the literature review of soil improvement, the specific methodology used for sample preparation and testing, and a detailed discussion of the experimental results.
Which keywords define this work?
Key terms include marine clay, soil stabilization, lime, cement, UCS, CBR, and geotechnical properties.
Why is cement found to be more stable than lime in this study?
The study concludes that cement is more stable under ponding conditions because it gains hardness through chemical reactions, whereas lime may dissolve or fade in the presence of excessive water.
How does the curing period affect the test results?
The results show that increased curing periods, particularly up to 28 days, lead to significant improvements in both the unconfined compressive strength and the CBR values of the treated marine clay.
